'According to the Flesh' in the Bible

who was of the seed of David, according to the flesh, But declared the Son of God with power, according to the Spirit of holiness, by the resurrection from the dead,

What shall we say then? That our father Abraham hath found according to the flesh?

Whose are the fathers, and from whom, according to the flesh, Christ came, who is, over all, God, blessed for ever.

Now when I was thus minded, did I use levity? or the things which I purpose, do I purpose according to the flesh, so that there should be with me yea and nay?

Servants, obey your masters according to the flesh, with fear and trembling, in singleness of heart, as unto the Lord:

Servants, obey in all things your masters according to the flesh; not with eye-service, as men-pleasers, but in singleness of heart, fearing God.
