Isaiah 47:6

I was wroth with my people— The metaphor in this verse is taken from a father, who being angry with his children delivers them up to chastisement; but his anger soon subsiding, and his affection reviving, he turns his indignation against those who had executed his commands, in such a manner as to punish them immoderately and severely. The cruelty of the Babylonians is expressed by the strongest term, namely, their oppression of the ancient, the old and feeble, whose venerable grey hairs should be their sufficient protection.
