For the ‘wickedness’ of demanding a king, during the wheat harvest Samuel calls on Yahweh to send thunder and rain; which he duly does. This comes at the culmination of a speech in which the seer condemns the worship of the Baals and Astartes — the gods of the land, and it is interesting in that Ba'al is the Canaanite god of kingship, fertility, and weather. The worship of Yahweh alone is clearly a later interpolation. However, it seems entirely plausible that this addiction is rather a revision of an identification of Yahweh with Ba'al. It is, after all, Yahweh who is called upon at the Canaanite high place (bamah) at Gilgal during the wheat harvest to send rain — a disaster for the crop. As an interplay between Yahweh and Ba'al, this text is clearly related to the contest between Elijah and the prophets of Ba'al (1 Kings 18:20-40). The wheat harvest is a time of rejoicing. This, coupled with the sacrifices and feast to celebrate the kingship of Saul, is a great feast which Samuel has turned into mourning. Samuel has quite actually rained on their parade.
