The world has just been created. No one is yet ruling. Two gods want to: Baal and Yamm. They go to El to ask for his judgment and wisdom. El chooses Yamm to be the first King of Earth. Yamm builds himself a palace and has a wonderful time. Eventually, he begins to get very arrogant. He sends messengers to Har Mo'ed to tell the gods he demands tribute. The gods are uneasy; Baal is furious. Ashtoreth says she can solve the problem.
She dresses up in her greatest finery and goes to talk Yamm out of his foolishness. She struts back and forth on the shore in front of the ocean to lure Yamm out. He doesn't come. She begins to undress (a strip tease) until eventually he comes out. He dispatches his messengers immediately saying he demands tribute AND Ashtoreth as his consort. Baal leaps up and drives the messengers out of Har Mo'ed, kicking their backsides as they go, saying he will destroy Yamm. The other gods praise his courage, given Yamm's greater size and strength. Baal worries. He goes to Kothar and asks him for weapons that will make him equal to Yamm. Kothar makes two weapons (axes or hammers) which, when thrown, will go straight to their mark and then return to Baal's hand (thunderbolts). He goes to Earth armed and stands on the seashore screaming insults until Yamm is furious and comes slithering up out of the ocean. Baal throws the first hammer, hits Yamm between the eyes, and knocks him out cold. Baal goes up to Yamm to kill him. Anat appears and says it will give him no glory to kill an unconscious victim. So Baal kicks him back into the ocean, throws a net over him, and stakes the net down to the ocean floor. Now Baal becomes King of Earth.
Baal vs.Yamm - young god borrows weapons, imprisons the great primeval chaotic ocean and then kills it (Marduk vs.Tiamat, Enki vs.Apsu, etc. -- archetype)
