'Companion' in the Bible

Have you not lately called to Me, “My Father.You were my friend in my youth.

Surely as a woman treacherously departeth from her companion, so have ye dealt treacherously with me, O house of Israel, saith Jehovah.

Hear then the word of Jehovah, ye women, and let your ear receive the word of his mouth, and teach your daughters wailing, and each one her companion lamentation.
