Which Gods interfere in the order to finally end the fight and bloodshed and how and by whom is Eupithes killed in book 24

Laertes kills Eupeithes; the scene is described below.

"Laertes was delighted when he heard this. "Good heavens, he exclaimed, "what a day I am enjoying: I do indeed rejoice at it. My son and grandson are vying with one another in the matter of valour."

On this Minerva came close up to him and said, "Son of Arceisius- best friend I have in the world- pray to the blue-eyed damsel, and to Jove her father; then poise your spear and hurl it."

As she spoke she infused fresh vigour into him, and when he had prayed to her he poised his spear and hurled it. He hit Eupeithes' helmet, and the spear went right through it, for the helmet stayed it not, and his armour rang rattling round him as he fell heavily to the ground."
