'Stamp' in the Bible

For men of that stamp are not bondservants of Christ our Lord, but are slaves to their own appetites; and by their plausible words and their flattery they utterly deceive the minds of the simple.

For men of this stamp are sham apostles, dishonest workmen, assuming the garb of Apostles of Christ.

and their teaching will spread like a running sore. Hymenaeus and Philetus are men of that stamp.
