Philippians 2:3-8

let nothing be in the spirit of strife or vain glory, but, in lowliness of mind, each esteeming the other as more excellent than themselves; regarding not each his own qualities, but each those of others also. For let this mind be in you which was also in Christ Jesus; who, subsisting in the form of God, did not esteem it an object of rapine to be on an equality with God; but emptied himself, taking a bondman's form, taking his place in the likeness of men; and having been found in figure as a man, humbled himself, becoming obedient even unto death, and that the death of the cross.
