Joshua made peace with them - Joshua agreed to receive them into a friendly connection with the Israelites, and to respect their lives and properties; and the elders of Israel bound themselves to the observance of it, and confirmed it with an oath. As the same words are used here as in Joshua 9:6, we may suppose that the covenant was made in the ordinary way, a sacrifice being offered on the occasion, and its blood poured out before the Lord. See on Genesis 15:10 (note), etc.

And Joshua made peace with them,.... Upon the report the princes made of having examined what they had said, and which they found to be true, particularly concerning their victuals:

and made a league with them, to let them live; and not destroy them as he did the Canaanites, and was ordered to do; they being supposed not to belong to them by the representation of things they had made:

and the princes of the congregation sware unto them; that they would keep the league and covenant they had made with them inviolable; they ratified it by an oath, which was a sacred solemn thing.

So Joshua made (granted) them peace (vid., Isaiah 27:5), and concluded a covenant with them (להם, in their favour), to let them live; and the princes of the congregation sware unto them. Letting them live is the only article of the league that is mentioned, both because this was the main point, and also with special reference to the fact that the Gibeonites, being Canaanites, ought properly to have been destroyed. It is true that Joshua and the princes of the congregation had not violated any express command of God by doing this; for the only thing prohibited in the law was making treaties with the Canaanites, which they did not suppose the Gibeonites to be, whilst in Deuteronomy 20:11, where wars with foreign nations (not Canaanites) are referred to, permission is given to make peace with them, so that all treaties with foreign nations are not forbidden. But they had failed in this respect, that, trusting to the crafty words of the Gibeonites, and to outward appearances only, they had forgotten their attitude to the Lord their God who had promised to His congregation, in all important matters, a direct revelation of His own will.

And Joshua made peace with them, and made a league with them, to let them live: and the princes of the congregation sware unto them.

9:15 To let them live - That is, they should not destroy them. That this league was lawful and obliging, appears, Because Joshua and all the princes, upon the review concluded it so to be, and spared them accordingly. Because God punished the violation of it long after, 2Sam 21:1. Because God is said to have hardened the hearts of all other cities, not to seek peace with Israel, that so he might utterly destroy them, Jos 11:19,20, which seems to imply that their utter destruction did not necessarily come upon them by virtue of any peremptory command of God, but by their own obstinate hardness, whereby they refused to make peace with the Israelites.

9:14-21 The Israelites, having examined the provisions of the Gibeonites, hastily concluded that they confirmed their account. We make more haste than good speed, when we stay not to take God with us, and do not consult him by the word and prayer. The fraud was soon found out. A lying tongue is but for a moment. Had the oath been in itself unlawful, it would not have been binding; for no obligation can render it our duty to commit a sin. But it was not unlawful to spare the Canaanites who submitted, and left idolatry, desiring only that their lives might be spared. A citizen of Zion swears to his own hurt, and changes not, Ps 15:4. Joshua and the princes, when they found that they had been deceived, did not apply to Eleazar the high priest to be freed from their engagement, much less did they pretend that no faith is to be kept with those to whom they had sworn. Let this convince us how we ought to keep our promises, and make good our bargains; and what conscience we ought to make of our words.
