Easton's Bible Dictionary (1897)
” It was used for felling trees (Isa. 10:34) and hewing timber for building. It is the rendering of a different word in Judg. 9:48, 1 Sam. 13:20, 21, Ps. 74:5, which refers to its sharpness. In 2 Kings 6:5 it is the translation of a word used with reference to its being made of iron. In Isa. 44:12 the Revised Version renders by “axe” the Hebrew maatsad, which means a “hewing” instrument. ” The “battle-axe” (army of Medes and Persians) mentioned in Jer. 51:20 was probably, as noted in the margin of the Revised Version, a “maul” or heavy mace.
