“And when they heard that, they lifted up their voice to God with one accord, and said, Lord, thou art God, which hast made heaven, and earth, and the sea, and all that in them is:”
King James Version (KJV)
4:24 The sense is, Lord, thou hast all power. And thy word is fulfilled. Men do rage against thee: but it is in vain.
Ac 4:24 Lifted up their voice to God with one accord. All engaged in prayer. It was a time of trial. They were forbidden, under awful threats, to preach Christ (Ac 4:18,21). Hence they go to God.
