Note 3 at Mt. 21:16: Jesus is quoting the scripture from Psalm 8:2 (see parallel scripture for this verse, p. 365). By comparing Jesus' quote with the actual passage in Psalm 8:2, we can see that Jesus substituted the word "praise" for the word "strength." Therefore, this is the scripture commenting on itself and likening praise to strength.

Notice also that Psalm 8:2 goes on to say that this praise or strength is because of God's enemies, that He might still the enemy and the avenger. So we can see by comparing these scriptures that praise is strength, and is intended to be used in spiritual warfare to stop Satan, our enemy. Satan cannot stand true praise to God (see note 4 at Mt. 4:9, p. 38).
