In the days of your gladness — Days appointed for rejoicing and thanksgiving to God for former mercies, or deliverances. Your solemn days — Your stated festivals. For a memorial — That God may remember you for good to accept and bless you. God then takes pleasure in our religious exercises, when we take pleasure in them. Holy work should be done with holy joy.

10 Also in the day of your gladness, and in your solemn days, and in the beginnings of your months, ye shall blow with the trumpets over your burnt offerings, and over the sacrifices of your peace offerings; that they may be to you for a memorial before your God: I am the LORD your God.
