Truly I say to you

"I tell you the truth." This adds emphasis to what Jesus says next.

you

All occurrences of this word are plural. (See: rc://en/ta/man/translate/figs-you)

whatever things you bind on earth will be bound in heaven; and whatever you release on earth will be released in heaven

Here "bind" is a metaphor meaning to forbid something, and "release" is a metaphor meaning to allow something. Also, "in heaven" is a metonym that represents God himself. See how you translated similar phrases in Matthew 16:19. Alternate translation: "God in heaven will approve whenever you forbid or allow something on earth" (See: rc://en/ta/man/translate/figs-metaphor and rc://en/ta/man/translate/figs-metonymy)
