Thus says Yahweh: "For three transgressions of Edom, yes, for four, I will not turn away its punishment; Because he pursued his brother with the sword, And cast off all pity, And his anger raged continually, And he kept his wrath forever;
Now He doesn't name three indictments towards each. "For three transgressions, and for four" is a figure of speech that's just declaring a cup of God's indignation is full and is going to overflow now in judgment against Damascus. Damascus is the first, the capital of Syria.
