Christ bought us back from the curse [caused by our not obeying all the requirements] of the Law of Moses; He became a curse for us [by dying on the cross], for it is written [Deut. 21:23], “Every one who hangs on a tree [i.e., a cross] is cursed [i.e., cut off from God].”
Jesus took upon Himself our sins [when] His body was placed upon the cross so that we, [through] dying to [i.e., giving up] the sinful life, would live for righteousness. You were healed [from your sins] by His being brutally treated.
And we [apostles] are witnesses of all that He did, both in the region where Jews lived and in Jerusalem [as well]. But they killed Him by hanging Him on a tree [i.e., the cross].
And he said [to me], ‘The God of our forefathers has appointed you to know His will and to see the Righteous One [i.e., Jesus], and to hear His voice [speaking to you].
and has now fulfilled to [us], their children, in raising up Jesus [to be the Messiah], just as it was written in the second Psalm [2:7]: ‘You [i.e., Jesus] are my Son; this day I have become Your Father.’
You [Jews] were the first ones to receive this blessing when God raised up [i.e., selected] His Servant [i.e., Jesus] and sent Him to turn all of you [away] from your sins.”
