'Yoke' in the Bible

and it shall be, that the city which is nearest to the slain man, even the elders of that city shall take a heifer of the herd, which hasn't been worked with, and which has not drawn in the yoke;

therefore you shall serve your enemies whom Yahweh shall send against you, in hunger, and in thirst, and in nakedness, and in want of all things: and he shall put a yoke of iron on your neck, until he has destroyed you.
