The Philistines from the maritime plain had made incursions into "the Hebrew upland for the purposes of plunder, when one of this" "name, the son of Anath, otherwise unknown, headed a rising for" the purpose of freeing the land from this oppression. He "repelled the invasion, slaying 600 men with an "ox goad" (q.v.)." "The goad was a formidable sharpointed instrument, sometimes ten" feet long. He was probably contemporary for a time with Deborah and Barak (Judg. 3:31; 5:6).
