The wrath of the enemy, i.e. their rage against me, as it is expressed Isaiah 37:28,29; their insolent and furious reproaches against my name, as if I were unnatural and cruel to my people, or unable to deliver them. Compare Exodus 32:12 Numbers 14:13 Deuteronomy 9:28 Joshua 7:9. The fear hereof is ascribed to God after the manner of men. Strangely, i.e. insolently and arrogantly, above what they used to do. Or, make themselves strangers, i.e. either really not acknowledge, or pretend they did not know, that which I had publicly declared, and they either did or easily might have known, to wit, that this judgment was inflicted upon them by my hand for their sins.
