Holiness also requires the keeping of the Sabbath. The setting apart of the Sabbath is the first step towards holiness in a child’s spiritual life. The Sabbath was the sign of the Mosaic covenant and was to be celebrated in the proper manner.
3 Every one of you shall revere his mother and his father, and you shall keep my Sabbaths: I am the LORD your God.
