'Seen' in the Bible

Now Jonathan and Ahimaaz were staying by En-rogel; and a maid-servant used to go and tell them; and they went and told king David: for they might not be seen to come into the city.

Then said Joab to the Cushite, Go, tell the king what thou hast seen. And the Cushite bowed himself unto Joab, and ran.

And he rode upon a cherub, and did fly; Yea, he was seen upon the wings of the wind.
