Acts 3:7

Lifted him up. Peter’s gesture came as a kindly aid to the childlike and perhaps only now dawning faith of the lame man. It was a transitional aid, spanning the momentary gulf between the last moment of the man’s helplessness and the first moment of his acceptance by faith of the fact that a miracle had been performed upon him. As did Peter, so are the children of God to do: “Strengthen . . . the weak hands, and confirm the feeble knees” (Isa. 35:3).

Ankle bones. Rather, “ankles.” Luke was a physician (Col. 4:14), and thus it is here a writer with medical experience who describes precisely what happened to the lame man.

Received strength. Rather, “were made firm.” The weak and flabby tendons and muscles were made strong and active.
