Selected original section: Pair of oxen sense
(3.) In 1 Sam. 11:7, 1 Kings 19:21, Job 1:3 the word thus translated is tzemed, which signifies a pair, two oxen yoked or coupled together, and hence in 1 Sam. 14:14 it represents as much land as a yoke of oxen could plough in a day, like the Latin jugum. In Isa. 5:10 this word in the plural is translated "acres."
