The figurative language in this excerpt means: He had many arrows and let them all fall at his feet.
Explanation:
Figurative language is that by which a word expresses an idea using other terms, thus appealing to a similarity, be it real or imaginary. Figurative language opposes literal language, since it uses words with their true meaning, that is, it refers to things as they are.
In this case, the expression "He poured out his feet to the rain of arrows from the quiver" in a literally meaningful language would mean that it rained arrows, but as the phrase was written in figurative language it means "He had many arrows and let them all fall at his feet. "
Odysseus has just revealed himself to the suitors, and the pouring out of the arrows ‘like rain’ shows everyone there that he has ample ammunition - they are as many as drops of rain. It also forewarns the rapidity and ease with which the arrows will be dispatched.
From the four words given in the question, the word "consult" is the only word that suggests the expression of 'any attempt or action of learning'. To "consult" means to ask the meaning of something, to ask for something, to ask for help etc.
The other three words - Contradict means to oppose, Connive means to plan something illegal and lastly to confute means to prove something to be wrong.
