Leviticus 23:38 - Joseph Benson’s Commentary on the Old and New Testaments

Besides the sabbaths The offerings of the weekly sabbaths. God will not have any sabbath-sacrifice diminished because of the addition of others, proper to any other feast. And it is here to be noted, that though other festival days are sometimes called sabbaths, yet these are here called the sabbaths of the Lord, in the way of contradistinction, to show that these were more eminently such than other feast-days. Your gifts Which, being here distinguished from the free-will-offerings made to the Lord, may denote what they freely gave to the priests over and above their first-fruits and tithes or other things which they were enjoined to give.
