Ibn Ezra on Ki Sisa 34:11

English: OBSERVE THOU. I believe that the Lord is addressing Moshe. 155 In other words, thou refers to Moshe. God is telling Moshe to keep these things 156 Transmit the exact contents. I.E. explains They kept (shameru) His testimonies (Ps. 99:7) to mean Moshe and Aharon transmitted the exact contents of God’s testimonies. They did not add or diminish anything from God’s dictum. See I.E. on Ps. 99:7. and to then relate them to the children of Israel. Shemor (observe) is to be taken in the sense of shameru (kept) in They 157 Moshe and Aharon. See I.E. on Ps. 99:7. kept His testimonies, and the statute that He gave them (Ps. 99:7), in accordance with the way I have explained it in its place. 158 See note
