Easton's Bible Dictionary: M. G. Easton, M.A., D.D.
An Old English word (from the Latin aro, I plough), meaning "ploughing." It is used in the Authorized Version in Gen. 45:6; Ex. 34:21; 1 Sam. 8:12; Dt. 21:4; Isa. 30:24; but the Revised Version has rendered the original in these places by the ordinary word to plough or till.
