And on all hills that shall be digged with the mattock, there shall not come thither the fear of briers and thorns: but it shall be for the sending forth of oxen, and for the treading of lesser cattle. KJV

And as for all the hills that used to be hoed with a hoe, you will not come there for fear of briers and thorns, but they will become a place where cattle are let loose and where sheep tread. ESV
