What the Bible says about Christ Taking form of a Servant
(From Forerunner Commentary)

Zechariah 3:8-9 Here the Branch is called God's Servant, taking away iniquity in one day. This is exactly what Christ did, and is reminiscent of Paul's description in Philippians 2:7: "But [Christ Jesus] made Himself of no reputation, taking the form of a servant. . . ." Richard T.
