‘And Yahweh said to the children of Israel.'
An unusual use in the predicate of ‘the children of Israel' used only when covenant matters were very much in mind. Here they had sought to renew the covenant, but Yahweh's reply was to be stern. He probably spoke through a prophet.
“Did I not deliver you from the Egyptians, and from the Amorites, from the children of Ammon, and from the Philistines?”
The Hebrew is difficult here but the sense is clear. Yahweh reminded them of all He had done for them in the past. The first from the Egyptians was the great deliverance. But this was followed by deliverance from the Amorites when they fought Sihon and Og (Numbers 21:21-35), from the children of Ammon (and Moab) in Judges 3:13, and from the Philistines by the hand of Shamgar (Judges 3:31).”
