'Mighty Deeds' in the Bible

Benaiah the son of Jehoiada, the son of a courageous man of Kabzeel who had done great things, killed the two sons of Ariel of Moab. Also he went down and killed a lion in a pit on a snowy day.

Who can put into words the mighty deeds of the Lord?Or who can proclaim all His praise [that is due Him]?

To make known to the sons of men Your mighty actsAnd the glorious majesty of Your kingdom.
