18 On the first day hold a sacred assembly and do no regular work.
18 In the first day shall be an holy convocation; ye shall do no manner of servile work therein:
18 On the first day there shall be a holy convocation. You shall not do any ordinary work,
18 Begin the first day in holy worship; don't do any regular work that day.
18 On the first day you shall have a holy convocation. You shall do no customary work.
18 The first day of the festival will be an official day for holy assembly, and no ordinary work may be done on that day.
Matthew Henry's Commentary on Numbers 28:18
Commentary on Numbers 28:16-31
(Read Numbers 28:16-31)
By the sacrifices enjoined in this chapter, we are reminded of the continued power of the sacrifice of Christ, and of our continual need to depend thereon. No hurrying employments, or perilous situations, or prosperous circumstances, should cause slackness in our religious exercises; but should rather stir us up to greater diligence in seeking help from, or giving thanks to the Lord. And all is to be accompanied with repentance, faith is the Lord Jesus, and love to him, and to produce true holiness in our conduct towards all men; otherwise God will abhor our most solemn services and abundant devotions. And Christ is able to supply the wants of every day, every week, every month, every year, every ordinance, every case.
