Hebrews 13:10

“We have an altar, etc..] By which is meant, not the cross of Christ, on which he was crucified; nor the Lord's table, where his flesh and blood are presented to faith, as food, though not offered; but Christ himself, who is altar, sacrifice, and priest; he was typified by the altar of the burnt offering, and the sacrifice that was offered upon it; the altar was made of Shittim wood, and covered with brass, denoting the incorruptibleness, duration, and strength of Christ: the horns of it, at the four corners, were for refuge; whoever fled to it, and laid hold on them, were safe; so Christ is a refuge to his people, that come from the four corners of the earth; and who believe in him, and lay…”

Whereof they have no right to eat which serve the tabernacle - A part of the meat offered in sacrifice among the Jews became the property of the priests and Levites, and they had, by the Law, a right to this as a part of their support; see Leviticus…”

“On the former part of this verse, Heb 13:15-16 depend; on the latter, Heb 13:11-14. We have an altar - The cross of Christ. Whereof they have no right to eat - To partake of the benefits which we receive therefrom. Who serve the tabernacle - Who adhere to the Mosaic law. Hebrews 13:11”
