The Death Of Ahab And YHWH's Arrangements For The Disposal Of His Blood (1 Kings 22:35-38).
To his credit Ahab recognised that his absence from the battlefield would be a blow to his army's morale, and having had his wound patched up, returned in his chariot into the fray, having in some way been provided with some means of support because of his weakness due to loss of blood. The battle continued to get ever more severe, but he was losing blood fairly rapidly and having fought until eventide he died, and his blood as he was dying, continually ran from his wound into the bottom of the chariot. It would have been a gory sight.
It is quite possible that through his bravery Ahab enabled his forces to gain the victory. But once the news got around at sunset that Ahab was dead, the people left the site of the battle (it was after all Ahab's battle), and returned to their own homes. (The prophetic author was only interested in the fact that Ahab had died as YHWH had prophesied, not in the course of the battle, but in view of Micaiah's earlier prophecy we can assume that he intended it to be seen that Israel did succeed in their object).
And while Ahab was no doubt buried with honours the writer makes clear what happened to his blood. It was dishonoured by being licked up by the scavenger dogs and by being washed away in the dirty water in which common prostitutes had washed themselves. Given the importance of the blood to YHWH (all blood had to be offered up to YHWH) this was an indication of Ahab's total rejection by YHWH. He was being declared to be ‘unclean'.
Analysis.
a And the battle increased that day, and the king was stayed up in his chariot against the Aramaeans (Syrians), and died at eventide, and the blood ran out of the wound into the bottom of the chariot (1 Kings 22:35).
b And there went a cry throughout the host about the going down of the sun, saying, “Every man to his city, and every man to his country.” (1 Kings 22:36).
a So the king died, and was brought to Samaria, and they buried the king in Samaria. And they washed the chariot by the pool of Samaria, and the dogs licked up his blood (now the common prostitutes washed themselves there), in accordance with the word of YHWH which he spoke (1 Kings 22:37-38).
Note that in ‘a' Ahab's blood flowed into his chariot, and in the parallel that blood was licked up by scavenger dogs and washed away in waters made ‘unclean' by common prostitutes. Centrally in ‘b' the people returned home in a state of peace and wellbeing. YHWH had granted them His blessing even while he worked out His judgment on Ahab.
‘ And the battle increased that day, and the king was stayed up in his chariot against the Aramaeans (Syrians), and died at eventide, and the blood ran out of the wound into the bottom of the chariot.'
With Ahab wounded the battle hotted up, and to his credit Ahab recognised that without his presence to encourage them (if they had thought that he was dead they would have withdrawn from the battle) his forces would have been hamstrung. So he had himself patched up, and returned to the battle in his chariot held upright by supports provided because he was weak through loss of blood, and he continued playing a part in the battle all day (he would have had an expert spearman with him in his chariot).
But the blood continued to seep out from his bandaged wound, and as the battle approached its end at eventide he died, with his blood staining the chariot.
‘ And there went a cry throughout the host about the going down of the sun, saying, “Every man to his city, and every man to his country.” '
Once the news of his death reached the people at sunset, the battle probably having been won (so Micaiah's prophecy), they recognised that in accordance with custom, with the planner and organiser of the invasion slain, the invasion was to be seen as over until there was a new king to determine the next action. Accordingly the army (which was not a professional army) disbursed back to their own homes. After all they had only fought because commanded to do so by the king, and now he was dead, it relieved them of their responsibility. They could now get back to seeing to their fields and cattle. The professional soldiers, and the men of Judah, could see to any necessary clearing up.
‘ So the king died, and was brought to Samaria, and they buried the king in Samaria.'
Meanwhile the king died, and his body was brought back to Samaria, and was buried with honour in Samaria. All seemed well, at least from that point of view.
‘ And they washed the chariot by the pool of Samaria, and the dogs licked up his blood (now the common prostitutes washed themselves there), in accordance with the word of YHWH which he spoke.'
But he was not honoured by YHWH. YHWH's view of Ahab was revealed by what happened to his blood. This had stained the bottom of the chariot. The chariot was thus taken to the pool of Samaria, probably a catchment area outside the walls, where it was washed, while the scavenger dogs gathered round to lick Ahab's blood. While not a literal fulfilment of the prophecy which had stated that this would happen in Jezreel because of the treatment of Naboth (a prophecy (1 Kings 21:19) that had been specifically transferred to his son because of Ahab's repentance (1 Kings 21:29), and would be fulfilled in 2 Kings 9:25-26), it was a partial fulfilment which brought disgrace on Ahab as well. This would be seen as an indication that his repentance, which had earned the delay, had proved not to be lasting, and thus he shared in the punishment. The remainder of his blood was washed away into the pool where the common prostitutes bathed themselves. There was thus a double disgrace. (Compare how dogs and prostitutes were both paralleled as unclean in Deuteronomy 23:18).
In Leviticus 17:11-14 we are told that, ‘the life of the flesh is in the blood' which was why what happened to the blood was considered to be so important. So for this to happen to Ahab's blood was a severe judgment on him.
