Great was the indignation of the Israelites as they learned the deception that had been practiced upon them. And this was heightened when, after three days’ journey, they reached the cities of the Gibeonites, near the center of the land. “All the congregation murmured against the princes;” but the latter refused to break the treaty, though secured by fraud, because they had “sworn unto them by the Lord God of Israel.” “And the children of Israel smote them not.” The Gibeonites had pledged themselves to renounce idolatry, and accept the worship of Jehovah; and the preservation of their lives was not a violation of God's command to destroy the idolatrous Canaanites. Hence the Hebrews had not by their oath pledged themselves to commit sin. And though the oath had been secured by deception, it was not to be disregarded. The obligation to which one's word is pledged—if it do not bind him to perform a wrong act—should be held sacred. No consideration of gain, of revenge, or of self-interest …
"Lying lips are abomination to the Lord: but they that deal truly are his delight."
Ellen White directly references Proverbs 12:22 in this passage.
"Who shall ascend into the hill of the Lord? or who shall stand in his holy place?"
Ellen White directly references Psalms 24:3 in this passage.
"The Gibeonites were permitted to live, but were attached as bondmen to the sanctuary, to perform all menial services. “Joshua made them that day hewers of wood and drawers of water for the congregation, and for the altar of the Lord.” These conditions they gratefully accepted, conscious that they had been at fault, and glad to purchase life on any terms. “Behold, we are in thine hand,” they said to Joshua; “as it seemeth good and right unto thee to do unto us, do.” For centuries their descendants were connected with the service of the sanctuary. PP 506.2"
"And Joshua made them that day hewers of wood and drawers of water for the congregation, and for the altar of the Lord, even unto this day, in the place which he should choose."
The EGW passage directly quotes and elaborates on Joshua 9:27, making it an explicit allusion.
"The territory of the Gibeonites comprised four cities. The people were not under the rule of a king, but were governed by elders, or senators. Gibeon, the most important of their towns, “was a great city, as one of the royal cities,” “and all the men thereof were mighty.” It is a striking evidence of the terror with which the Israelites had inspired the inhabitants of Canaan, that the people of such a city should have resorted to so humiliating an expedient to save their lives. PP 506.3"
"That they feared greatly, because Gibeon was a great city, as one of the royal cities, and because it was greater than Ai, and all the men thereof were mighty."
The EGW passage directly quotes and expands upon the description of Gibeon found in Joshua 10:2.
