Charles Ellicott Commentary Acts 3:8

"And leaping up, he stood, and began to walk; and he entered with them into the temple, walking, and leaping, and praising God." — Acts 3:8 (ASV)

And he leaping up stood.—The verb is a compound form of that in the Septuagint of Isaiah 35:6—The lame shall leap as a hart. First there was the upward leap in the new consciousness of power; then the successful effort to stand for the first time in his life; then he began to walk, and went on step by step; then the two-fold mode of motion, what to others was the normal act of walking, alternating with the leaps of an exuberant joy.

And so he entered with them into the Temple, i.e., into the Court of Women, upon which the Beautiful Gate opened. At this hour, the hour of the evening sacrifice, it would be naturally filled with worshippers.
