Thou art my battle axe and weapons of war: for with thee will I break in pieces the nations, and with thee will I destroy kingdoms;
Thou art my battle-ax ... - (note, Jeremiah 50:23).
With thee will I break in pieces the nations. "Break in pieces" refers to the "hammer" there (cf. Nahum 2:1, "He that dasheth in pieces is come up," margin, 'the disperser, or hammer'). The club also was often used by ancient warriors.
