King James Version: 5 Let this mind be in you, which was also in Christ Jesus: 6 Who, being in the form of God, thought it not robbery to be equal with God: 7 But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men:
Revised Standard Edition: 5 Have this mind among yourselves, which is yours in Christ Jesus, 6 who, though he was in the form of God, did not count equality with God a thing to be grasped, 7 but emptied himself, taking the form of a servant, being born in the likeness of men.
Darby: 5 For let this mind be in you which [was] also in Christ Jesus; 6 who, subsisting in the form of God, did not esteem it an object of rapine to be on an equality with God; 7 but emptied himself, taking a bondman's form, taking his place in [the] likeness of men;
New World Translation: Keep this mental attitude in YOU that was also in Christ Jesus, 6 who, although he was existing in God's form, gave no consideration to a seizure, namely, that he should be equal to God. 7 No, but he emptied himself and took a slave's form and came to be in the likeness of men.
