Matthew 23:15

15. Proselyte The THIRD WOE is pronounced upon their efforts to extend their unhallowed dominion. The Jews were very zealous to make proselytes, and in our Saviour’s day were not a little successful. Twofold more the child of hell They did not sanctify the proselyte from his old heathen vices, and they imparted to him new Jewish wickedness.

A proselyte was a convert from heathenism to Judaism. Proselytes have usually been divided into proselytes of righteousness, which included all who went so far as to worship the true God and observe the practice of primitive morality; and proselytes of the gate, including those who entered completely into Judaism by circumcision and the assuming the obligations of the whole Mosaic ritual. This is, however, comparatively a modern division.
