Exodus 21
Young's Literal Translation (YLT)
36 or, it hath been known that the ox is `one' accustomed to gore heretofore, and its owner doth not watch it, he certainly repayeth ox for ox, and the dead is his.
Bible in Basic English (BBE)
36 But if it is common knowledge that the ox has frequently done such damage in the past, and its owner has not kept it under control, he will have to give ox for ox; and the dead beast will be his.
