“Because you had a perpetual enmity, and have poured out the children of Israel to the power of the sword in the time of their calamity, in the time of the final iniquity (iniquity of the end).”
This is the reason for their condemnation, their perpetual enmity towards the people of God, vividly again revealed in recent days. In mind therefore is their perpetual enmity and betrayal. It is clear continually that Edom did have a perpetual enmity against Israel and Judah. See Genesis 25:22-34; Genesis 27:1-41; Genesis 36:1; Numbers 20:14-21; Numbers 24:15-19; 1 Samuel 14:47; 2 Samuel 8:13-14; 1Ki 11:14-22; 2 Kings 8:21; 2 Kings 14:7; 2 Chronicles 20:1-23; 2 Chronicles 28:17; Psalms 137:7; Isaiah 1:11-16; Isaiah 34:1-17; Jeremiah 49:7-22; Lamentations 4:21-22; Daniel 11:41; Amos 1:11-12; Obadiah 1:10-14; Malachi 1:2-5). They were constant enemies.
But especially in mind are their cold, cynical acts when Judah desperately needed help. Ammon received refugees, Egypt received refugees, but Edom did not. They turned them back at the frontiers. This is probably what is in mind in their ‘pouring out of the children of Israel to the power of the sword'. It may, however, refer to their subsequent invasion of the land (see Ezekiel 35:10).
‘In the time of their calamity, in the time of the final iniquity.' This almost certainly refers to the fall of Jerusalem, and the subsequent events that followed when Israel perpetrated their final iniquity.
