1 Kings 20:11 Meaning and Commentary

Ver. 11 And the king of Israel answered and said
Very mildly and very wisely:

tell him, let not him that girdeth on his harness boast himself as he
that putteth it off;
that is, he that prepares for the battle as he that has got the victory; the sense is, let no man triumph before the battle is over and the victory won; the events of war are uncertain; the battle is not always to the strong.
