Joshua 9:18

And the children of Israel smote them not, because the princes of the congregation had sworn unto them by the LORD God of Israel. And all the congregation murmured against the princes.

Ver. 18. Smote them not.] But yet bore them on their backs, as we say, and murmured against the princes who were gulled by the Gibeonites, and the people by that means beguiled of the spoil of those great cities.

Because the princes … had sworn unto them.] ορκος quasi ερκος; an oath is a hedge which must not be lept over for the avoiding of a piece of fouler way. If the Gibeonites had been slain after an oath given for their security, the banks of blasphemy would have been broken down in those heathens that had heard of it.
