'Knew' in the Bible

Therefore, [because he] was a prophet and knew that God had sworn to him with an oath to seat {one of his descendants} on his throne,

Paul wanted this one to go with him, and he took [him] [and] circumcised him because of the Jews who were in those places, for [they] all knew that his father was Greek.

This man had been instructed [in] the way of the Lord, and being enthusiastic in spirit, he was speaking and teaching accurately the [things] about Jesus, [although he] knew only the baptism of John.
