'Children of Israel' in the Bible

when he was full forty years old, he took the resolution to visit his brethren the children of Israel.

this is that Moses who said to the children of Israel, "a prophet shall the Lord your God raise up unto you of your brethren, like unto me; him shall ye hear."

go, said the Lord to him: for he is the instrument I have chosen, to bear my name to the Gentiles, to kings, and to the children of Israel.

this was what he communicated to the children of Israel, proclaiming salvation by Jesus Christ, who is the Lord of all mankind.
