I say to you

This adds emphasis to what Jesus says next.

to you

Here "you" is plural. Jesus was speaking to the religious leaders and also to the Jewish people in general. (See: rc://en/ta/man/translate/figs-you)

the kingdom of God will be taken away from you and will be given to a nation that produces its fruits

Here "kingdom of God" refers to God's rule as king. This can be stated in active form. AT: "God will reject you, the Jewish people, and he will be king over people from other nations who bear fruit" (See: rc://en/ta/man/translate/figs-metonymy and rc://en/ta/man/translate/figs-activepassive)

that produces its fruits

This is an idiom that refers to obedience. AT: "that obeys God's commands" (See: rc://en/ta/man/translate/figs-idiom)

Whoever falls on this stone will be broken to pieces

Here, "this stone" is the same stone as in Matthew 21:42. This is a metaphor that means the Christ will destroy anyone who rebels against him. This can be stated in active form. AT: "The stone will break into pieces anyone who falls on it" (See: rc://en/ta/man/translate/figs-metaphor and rc://en/ta/man/translate/figs-activepassive)

But anyone on whom it falls will be crushed

This means basically the same thing as the previous sentence. It is a metaphor that means the Christ will have the final judgment and will destroy everyone who rebels against him. (See: rc://en/ta/man/translate/figs-parallelism and rc://en/ta/man/translate/figs-metaphor)
