'External' in the Bible

Instead He emptied Himselfby assuming the form of a slave,taking on the likeness of men.And when He had come as a manin His external form,

for we [who are born-again have been reborn from above—spiritually transformed, renewed, set apart for His purpose and] are the true circumcision, who worship in the Spirit of God and glory and take pride and exult in Christ Jesus and place no confidence [in what we have or who we are] in the flesh—
