Let their table become a net and a trap

"Table" here is a metonym that represents feasting, and "net" and "trap" are metaphors that represent punishment. You can translate this in an active form. Alternate translation: "Please, God, make their feasts like a trap that catches them" (See: rc://en/ta/man/jit/figs-metonymy and rc://en/ta/man/jit/figs-metaphor and rc://en/ta/man/jit/figs-activepassive)

a stumbling block

A "stumbling block" is anything that causes a person to trip so that he falls down. Here it represents something that tempts a person to sin. Alternate translation: "something that tempts them to sin" (See: rc://en/ta/man/jit/figs-metaphor)

a retribution for them

"something that allows you to take revenge on them"
