'Stray' in the Bible

“If you will return, O Israel,” says the Lord,“If you will return to Me,And if you will put away your detestable things and remove your man-made gods from My sight,And not stray or waver,

Israel is a stray lamb, chased by lions.The first who devoured him was the king of Assyria;the last one who crushed his boneswas Nebuchadnezzar king of Babylon.
