Answer:
The figurative language in this excerpt means: He had many arrows and let them all fall at his feet.
Step-by-step 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. "
