'Seen' in the Bible

Now Jonathan and Ahimaaz [the priests’ sons] were staying at En-rogel, and a maidservant [appearing to go for water] would go and tell them [what was happening], and they would go [secretly] and inform King David; for they could not [allow themselves to] be seen coming into the city [of Jerusalem].

Then Joab said to the Cushite (Ethiopian), “Go, tell the king what you have seen.” And the Cushite bowed to Joab and ran.

“He rode on a cherub and flew;He appeared upon the wings of the wind.
