Albert Barnes Commentary Amos 2:13

"Behold, I will press [you] in your place, as a cart presseth that is full of sheaves." — Amos 2:13 (ASV)

Behold, I am pressed under you - God bore His people, as the wagon bears the sheaves. “You yourselves have seen,” He said to them by Moses, how I bore you on eagle’s wings, and brought you to Myself (Exodus 19:4). You have seen how the Lord your God bore you, as a man bears his son, in all the way that you went, until you came into this place (Deuteronomy 1:31). And by Isaiah, He bore them and carried them all the days of old (Isaiah 63:9); and, which are born by Me from the belly, which are carried from the womb (Isaiah 46:3).

Now, He speaks of Himself as wearied by them, as by Isaiah, you have wearied Me with your iniquities (Isaiah 43:24); and by Malachi, you have wearied the Lord: yet you say, ‘How have we wearied Him?’ (Malachi 2:17). His long-suffering was, as it were, worn out by them. He was straitened under them, as the wagon groans under the sheaves with which it is overfull.

The words are literally: “Behold I, I” (emphatic I—your God, of whom it would seem impossible) “straiten Myself under you” (that is, of My own Will I allow Myself to be straitened under you), just “as the wagon full for itself” (that is, as full as it can ever contain) “is straitened, groans,” as we say.

God says (the word in Hebrew is half active) that He allows Himself to be straitened, as in Isaiah, He says, I am weary to bear, literally, “I let Myself be wearied.” We are simply passive under weariness or oppressiveness: God endures us, out of His own free condescension in enduring us. But it follows, that when He will cease to endure our many and grievous sins, He will cast them and the sinner away from Him.
