"None need fear that their liberality would bring them to want. Obedience to God's commandments would surely result in prosperity. “Thou shalt lend unto many nations,” He said, “but thou shalt not borrow; and thou shalt reign over many nations, but they shall not reign over thee.” Deuteronomy 15:6 . PP 533.1"
"The Lord shall open unto thee his good treasure, the heaven to give the rain unto thy land in his season, and to bless all the work of thine hand: and thou shalt lend unto many nations, and thou shalt not borrow."
EGW directly quotes Deuteronomy 15:6.
"For the Lord thy God blesseth thee, as he promised thee: and thou shalt lend unto many nations, but thou shalt not borrow; and thou shalt reign over many nations, but they shall not reign over thee."
Ellen White directly references Deuteronomy 15:6 in this passage.
"The liberal soul shall be made fat: and he that watereth shall be watered also himself."
Both passages connect generosity with prosperity, although the wording and specific promises differ. Proverbs 11:25 provides a general principle, while Deuteronomy 15:6 is a specific promise to Israel.
"“On the tenth day of the seventh month, in the Day of Atonement,” the trumpet of the jubilee was sounded. Throughout the land, wherever the Jewish people dwelt, the sound was heard, calling upon all the children of Jacob to welcome the year of release. On the great Day of Atonement satisfaction was made for the sins of Israel, and with gladness of heart the people would welcome the jubilee. PP 533.3"
"Then shalt thou cause the trumpet of the jubile to sound on the tenth day of the seventh month, in the day of atonement shall ye make the trumpet sound throughout all your land."
EGW is directly referencing and explaining Leviticus 25:9.
"And ye shall hallow the fiftieth year, and proclaim liberty throughout all the land unto all the inhabitants thereof: it shall be a jubile unto you; and ye shall return every man unto his possession, and ye shall return every man unto his family."
EGW elaborates on the concept of the Jubilee year and the liberty proclaimed, which is the core theme of Leviticus 25:10.
"As in the sabbatical year, the land was not to be sown or reaped, and all that it produced was to be regarded as the rightful property of the poor. Certain classes of Hebrew slaves—all who did not receive their liberty in the sabbatical year—were now set free. But that which especially distinguished the year of jubilee was the reversion of all landed property to the family of the original possessor. By the special direction of God the land had been divided by lot. After the division was made no one was at liberty to trade his estate. Neither was he to sell his land unless poverty compelled him to do so, and then, whenever he or any of his kindred might desire to redeem it, the purchaser must not refuse to sell it; and if unredeemed, it would revert to its first possessor or his heirs in the year of jubilee. PP 533.4"
"The land shall not be sold for ever: for the land is mine; for ye are strangers and sojourners with me."
EGW explains the concept of land reverting to the original owner in the Jubilee year, connecting it to the principle stated in Leviticus 25:23 that the land ultimately belongs to God.
