'Stranger' in the Bible

At the hearing of the ear they hearken to me, Sons of a stranger feign obedience to me,

Sons of a stranger fade away, And are slain out of their close places.

A stranger I have been to my brother, And a foreigner to sons of my mother.

How do we sing the song of Jehovah, On the land of a stranger?

Send forth Thy hand from on high, Free me, and deliver me from many waters, From the hand of sons of a stranger,

Free me, and deliver me From the hand of sons of a stranger, Because their mouth hath spoken vanity, And their right hand is a right hand of falsehood,
