Joshua 9:18 Meaning and Commentary

Joshua 9:18

And the children of Israel smote them not
The inhabitants of the four cities, when they came to them, though they found it to be a true report that was brought them of their being neighbours, and that they were imposed upon by them:

because the princes of the congregation had sworn unto them by the
Lord God of Israel;
by the Word of the Lord God of Israel, as the Targum, and therefore they restrained the people from smiting and plundering them; for it was not the oath of the princes the people so much regarded, or had such an influence on them as to abstain from seizing on them, but the princes, by reason of their oath, would not suffer them to touch them:

and all the congregation murmured against the princes;
not only for taking such an oath, but chiefly because they restrained them from smiting the Gibeonites, and taking their substance for a prey; their eager desire of revenge, and of seizing their goods, and inhabiting their cities, raised a murmur in them against the princes. This is to be understood not of the whole body of the people at Gilgal, but of all that party that was sent to Gibeon, and of the princes that went with them.

Joshua 9:18 In-Context

16 Three days after they had made the agreement, the Israelites learned that the Gibeonites lived nearby.

17 So the Israelites went to where they lived and on the third day came to their cities: Gibeon, Kephirah, Beeroth, and Kiriath Jearim.

18 But the Israelites did not attack those cities, because they had made a promise to them before the Lord, the God of Israel. All the Israelites grumbled against the leaders.

19 But the leaders answered, "We have given our promise before the Lord, the God of Israel, so we cannot attack them now.

20 This is what we must do. We must let them live. Otherwise, God's anger will be against us for breaking the oath we swore to them.
