'Themselves' in the Bible

Professing themselves to be wise, they became fools,

Therefore God also gave them up in the lusts of their hearts to uncleanness, that their bodies should be dishonored among themselves,

Likewise also the men, leaving the natural function of the woman, burned in their lust toward one another, men doing what is inappropriate with men, and receiving in themselves the due penalty of their error.

(for when Gentiles who don't have the law do by nature the things of the law, these, not having the law, are a law to themselves,

in that they show the work of the law written in their hearts, their conscience testifying with them, and their thoughts among themselves accusing or else excusing them)

For being ignorant of God's righteousness, and seeking to establish their own righteousness, they didn't subject themselves to the righteousness of God.

Therefore he who resists the authority, withstands the ordinance of God; and those who withstand will receive to themselves judgment.
