"Not far distant from where the Israelites were now encamped was the home of Jethro, the father-in-law of Moses. Jethro had heard of the deliverance of the Hebrews, and he now set out to visit them, and restore to Moses his wife and two sons. The great leader was informed by messengers of their approach, and he went out with joy to meet them, and, the first greetings over, conducted them to his tent. He had sent back his family when on his way to the perils of leading Israel from Egypt, but now he could again enjoy the relief and comfort of their society. To Jethro he recounted the wonderful dealings of God with Israel, and the patriarch rejoiced and blessed the Lord, and with Moses and the elders he united in offering sacrifice and holding a solemn feast in commemoration of God's mercy. PP 300.2"
"When Jethro, the priest of Midian, Moses’ father in law, heard of all that God had done for Moses, and for Israel his people, and that the Lord had brought Israel out of Egypt; Then Jethro, Moses’ father in law, took Zipporah, Moses’ wife, after he had sent her back, And her two sons; of which the name of the one was Gershom; for he said, I have been an alien in a strange land: And the name of the other was Eliezer; for the God of my father, said he, was mine help, and delivered me from the sword of Pharaoh: And Jethro, Moses’ father in law, came with his sons and his wife unto Moses into the wilderness, where he encamped at the mount of God: And he said unto Moses, I thy father in law Jethro am come unto thee, and thy wife, and her two sons with her. And Moses went out to meet his father in law, and did obeisance, and kissed him; and they asked each other of their welfare; and they came into the tent. And Moses told his father in law all that the Lord had done unto Pharaoh and to the Egyptians for Israel’s sake, and all the travail that had come upon them by the way, and how the Lord delivered them. And Jethro rejoiced for all the goodness which the Lord had done to Israel, whom he had delivered out of the hand of the Egyptians. And Jethro said, Blessed be the Lord, who hath delivered you out of the hand of the Egyptians, and out of the hand of Pharaoh, who hath delivered the people from under the hand of the Egyptians. Now I know that the Lord is greater than all gods: for in the thing wherein they dealt proudly he was above them. And Jethro, Moses’ father in law, took a burnt offering and sacrifices for God: and Aaron came, and all the elders of Israel, to eat bread with Moses’ father in law before God."
The EGW passage closely follows the narrative of Exodus 18:1-12, recounting Jethro's visit, the reunion with Moses' family, and the sacrifices offered.
"When Jethro, the priest of Midian, Moses’ father in law, heard of all that God had done for Moses, and for Israel his people, and that the Lord had brought Israel out of Egypt; Then Jethro, Moses’ father in law, took Zipporah, Moses’ wife, after he had sent her back, And her two sons; of which the name of the one was Gershom; for he said, I have been an alien in a strange land: And the name of the other was Eliezer; for the God of my father, said he, was mine help, and delivered me from the sword of Pharaoh: And Jethro, Moses’ father in law, came with his sons and his wife unto Moses into the wilderness, where he encamped at the mount of God: And he said unto Moses, I thy father in law Jethro am come unto thee, and thy wife, and her two sons with her."
The EGW passage is a retelling of the events described in Exodus 18:1-6, including Jethro's arrival, his family, and the reason for his visit. It's a clear and direct allusion.
As Jethro remained in the camp, he soon saw how heavy were the burdens that rested upon Moses. To maintain order and discipline among that vast, ignorant, and untrained multitude was indeed a stupendous task. Moses was their recognized leader and magistrate, and not only the general interests and duties of the people, but the controversies that arose among them, were referred to him. He had permitted this, for it gave him an opportunity to instruct them; as he said, “I do make them know the statutes of God, and His laws.” But Jethro remonstrated against this, saying, “This thing is too heavy for thee; thou art not able to perform it thyself alone.” “Thou wilt surely wear away,” and he counseled Moses to appoint proper persons as rulers of thousands, and others as rulers of hundreds, and others of tens. They should be “able men, such as fear God, men of truth, hating covetousness.” These were to judge in all matters of minor consequence, while the most difficult and important cases shou…
"And it came to pass on the morrow, that Moses sat to judge the people: and the people stood by Moses from the morning unto the evening. And when Moses’ father in law saw all that he did to the people, he said, What is this thing that thou doest to the people? why sittest thou thyself alone, and all the people stand by thee from morning unto even? And Moses said unto his father in law, Because the people come unto me to enquire of God: When they have a matter, they come unto me; and I judge between one and another, and I do make them know the statutes of God, and his laws. And Moses’ father in law said unto him, The thing that thou doest is not good. Thou wilt surely wear away, both thou, and this people that is with thee: for this thing is too heavy for thee; thou art not able to perform it thyself alone. Hearken now unto my voice, I will give thee counsel, and God shall be with thee: Be thou for the people to God-ward, that thou mayest bring the causes unto God: And thou shalt teach them ordinances and laws, and shalt shew them the way wherein they must walk, and the work that they must do. Moreover thou shalt provide out of all the people able men, such as fear God, men of truth, hating covetousness; and place such over them, to be rulers of thousands, and rulers of hundreds, rulers of fifties, and rulers of tens: And let them judge the people at all seasons: and it shall be, that every great matter they shall bring unto thee, but every small matter they shall judge: so shall it be easier for thyself, and they shall bear the burden with thee. If thou shalt do this thing, and God command thee so, then thou shalt be able to endure, and all this people shall also go to their place in peace. So Moses hearkened to the voice of his father in law, and did all that he had said. And Moses chose able men out of all Israel, and made them heads over the people, rulers of thousands, rulers of hundreds, rulers of fifties, and rulers of tens. And they judged the people at all seasons: the hard causes they brought unto Moses, but every small matter they judged themselves."
The EGW passage directly recounts the events and quotes from Exodus 18:13-26 regarding Jethro's advice to Moses about delegating authority.
"And it came to pass on the morrow, that Moses sat to judge the people: and the people stood by Moses from the morning unto the evening."
The EGW passage directly references the event of Moses judging the people all day, as described in Exodus 18:13, and Jethro's subsequent advice.
