Peter Pett's Commentary on the Bible
1 Kings 21:24
“ Him who dies of Ahab in the city the dogs will eat, and him who dies in the field will the birds of the heavens eat.”
A similar fate to some extent awaited all the house of Ahab, except in their case they would be allowed to die first. But their bodies would then be disgraced by being eaten by scavenger dogs or scavenger birds. They would receive no proper burial.
‘ (For there was none like Ahab, who sold himself to do what was evil in the sight of YHWH, whom Jezebel his wife stirred up. And he did very abominably in following idols, according to all that the Amorites did, whom YHWH cast out before the children of Israel).
The reason for this cruel end is given. It was because he had sinned above all who were before him. None had sinned as he had. He had sold himself to do evil in the sight of YHWH (compare 1 Kings 21:20) spurred on, and stirred up, by his wife Jezebel. And this had included his eager following of the idols of the Canaanites/Amorites whom YHWH had for that very reason cast out before the children of Israel. Ahab was not thus condemned just for following a foreign Baal at the behest of his wife, but for engaging in every form of local Baalism, and that included the false worship introduced by Jeroboam the son of Nebat where Yahwism and Baalism had been intermingled.
‘ And it came about, when Ahab heard those words, that he tore his clothes, and put sackcloth on his flesh, and fasted, and lay in sackcloth, and went tenderly.'
When Ahab heard these words he was genuinely moved. His heart was torn, something which he symbolised by tearing his clothes. And he divested himself of his royal robes and dressed in sackcloth, and went without food, and lay down before YHWH in sackcloth, and began to reform himself. Sackcloth was the clothing of the very poor, and was rough on the skin, especially sensitive royal skin. It was seen as a way of humbling oneself. Fasting (going without food in order to denote repentance) was another way of demonstrating sorrow. ‘Going tenderly' probably represents a temporary change of attitude and a willingness to consider YHWH's Laws and walk in them (being careful how he walked).
‘ And the word of YHWH came to Elijah the Tishbite, saying, “Do you see how Ahab humbles himself before me? Because he humbles himself before me, I will not bring the evil in his days, but in his son's days will I bring the evil on his house.” '
When YHWH saw his repentance, He pointed it out to Elijah and declared that because Ahab had humbled himself in this way the evil to his house would not come on him in his day, but would rather come in his son's days. Judgment would be delayed but not removed. (Of course had his sons repented then the judgment would have been even further delayed. But it was not to be - 1 Kings 22:52). This aspect of judgment must always be borne in mind. Judgment was always to be seen as avoidable by repentance, as long as the repentance was genuine. Thus judgment was always, at least temporarily, avoidable.
