Scripture does not record a single word Joseph ever spoke. But Joseph’s example of quiet faithfulness encouraged others to trust God.
Evidence for Hebrew Roots of Matthew 1:21

The oldest known manuscripts of the New Testament were written in Greek, but by comparing Matt. 1:21 in Hebrew, Aramaic and Greek with the knowledge of the naming formula so common in the Hebrew Bible, we see that this verse only makes sense in Hebrew. Since the naming formula depends on a wordplay that does not work in Greek or Aramaic, Matt. 1:21, or the oral tradition behind it, had to be in Hebrew.
