'Of the Flesh' in the Bible

I, therefore, brethren, have not been able to speak unto you, as unto men of the Spirit, but as unto men of the flesh - as unto babes in Christ: -

To deliver such a one as this, unto Satan, for the destruction of the flesh, - that, the spirit, may be saved in the day of the Lord.

If, however, thou shouldst even marry, thou hast not sinned; and, if one who is virgin should marry, that one hath not sinned; - but, tribulation of the flesh, shall, such, have: - howbeit, I, spare you.

If, we, unto you, the things of the Spirit have sown, is it a great matter, if, we, of you, the things of the flesh shall reap?
