Keil & Delitzsch

It was no real widowhood, however, but only an apparent one (Jer 51:5), for the husband of Jerusalem was living still, "For thy husband is thy Creator; Jehovah of hosts is His name; and thy Redeemer the Holy One of Israel; God of the whole earth is He called." The plurals בעליך and עשׂיך (see at Isa 22:11) are to be explained from the plural 'Elōhı̄m, which is connected with plural attributes in Jos 24:19; Sa1 17:26, Ps. 58:12 (compare מרימיו in Isa 10:15), and with plural predicates in Gen 20:13; Gen 35:7, and Sa2 7:23. By such expressions as these, which represent all the plurality of the divine nature as inherent in the One, the religion of revelation, both Israelitish and Christian, exhibits itself as embodying all that is true in polytheism. He who has entered into the relation of husband to Jerusalem (בעליך, not בעליך, Isa 1:3) is the very same through whom she first came into existence, the God whose bidding the heavenly hosts obey; and the Redeemer of Jerusalem, the Holy One of Israel, is called the God of the whole earth, and therefore has both the power and the means to help her, as prompted by the relation of love which exists between them.
