There came an angel of the LORD, and sat under an oak ... And the angel of the LORD appeared unto him, and said unto him, The LORD is with thee, thou mighty man of valour. Judges 6:11

Trivia: God stopped killing people for "committing whoredom with the daughters of Moab" because "his wrath was turned away" by a man who thrust a javelin through a man of Israel and a daughter of Moab.
