1 Corinthians 10:15

I speak as to wise men,.... That is, what he was now going to say concerning the Lord's supper, and the communion which believers have with Christ in it, which they as Christians must have knowledge of; and concerning the participation of the altar the Israelites had, who ate of the sacrifices of it, which many of them, being Jews, as such must know; and therefore being fully persuaded of the propriety and pertinency of the instances he was about to produce, and of the justness of his reasoning upon them, he appeals to the Corinthians, as men of wisdom and understanding in these things, and makes them themselves judges thereof:

judge what I say; consider and weigh the matter well, and you will discern and judge that what I say is proper and pertinent, just and right.
