Behold, the eyes of the Lord GOD are upon the sinful kingdom, and I will destroy it from off the face of the earth; saving that I will not utterly destroy the house of Jacob, saith the LORD.
Behold, the eyes of the Lord God are upon the sinful kingdom - i:e., I am watching all its sinful course, in order to punish it (cf. Amos 9:4, "I will set mine eyes upon them for evil, and not for good;" Psalms 34:15-16).
And I will destroy it from off the face of the earth; saving that I will not utterly destroy the house of Jacob - though, as a "kingdom," the nation is now utterly to perish, a remnant is to be spared for "Jacob" their forefather's sake (cf. Jeremiah 30:11, "Though I make a full end of all nations where I have scattered thee; yet will I not make a full end of thee"); to fulfill the covenant whereby "the seed of Israel" is hereafter to be "a nation before God forever" (Jeremiah 31:36).
