10:34 written in your law. This is quoted from Psalm 82:6. The generic term “law” was often understood by the Jews to include the entire Old Testament Canon of Scripture. See the notes on Psalm 82:1,6.

10:35 scripture cannot be broken. Jesus is here basing His entire defense against the charge of blasphemy on one word, “gods” in a relatively obscure psalm, commenting that the “scripture”—that is, the “writing,” the word actually written down—cannot be broken. This constitutes a very important testimony by Christ to the plenary verbal inspiration and authority of the Bible. The reasoning of Christ is very subtle, yet powerful, relying entirely on the use of this precise word in its context.

10:36 the Son of God. In Psalm 82:1, the word “gods” is the Hebrew elohim, the usual word for “God.” There, however, it is applied to human judges to whom the Word of God had come. However, the Word had never “come” to Jesus. He Himself was the Word, whom the Father had “sent into the world.” No mere man, not even a human judge, was ever sent into the world with such a mission, yet they had been called “gods.” These human judges, or “gods,” had been rebuked for failing to dispense true justice (Psalm 82:2), so God had sent His Son into the world to accomplish true justice, thereby fulfilling the prophecy of Psalm 82:8. Thus, if these fallible and unjust human judges had been called “gods” (supposedly acting in the name of the true God and Judge), then surely it was more appropriate by far for them to recognize Jesus as the Son of God.
