Thus saith the Lord of hosts - Jerome: “At each word and sentence, in which good things, for their greatness, almost incredible are promised, the prophet premises, “Thus saith the Lord of hosts,” as if he would say, Think not that what I pledge you are my own, and refuse me not credence as man. What I unfold are the promises of God.”
I was jealous - Literally, “I have been and am jealous for.” . He repeats in words slightly varied, but in the same rhythm, the declaration of tits tender love wherewith He opened the series of visions, thereby assuring beforehand that this was, like that, an answer of peace. The form of words shows, that this was a jealousy for, not with her; yet it was one and the same strong, yea infinite love, whereby God, as He says, “clave unto their fathers to love them and chose their seed after them out of all nations” Deuteronomy 10:15. His jealousy of their sins was part of that love, whereby, (Dionysius), “without disturbance of passion or of tranquillity, He inflicted rigorous punishment, as a man fearfully reproves a wife who sins.” They are two different forms of love according to two needs. Rup.: “The jealousy (Zelus) of God is good, to love people and hate the sins of people. Contrariwise the jealousy of the devil is evil, to hate people and love the sins of people.” Osorius: “Since God’s anger had its origin in the vehemence of His love (for this sort of jealousy arises from the greatness of love), there was hope that the anger might readily be appeased toward her.”
