The Hebrew people have been rescued by God from Egyptian slavery and brought to Mount Sinai to meet God. God is declaring to his people the Ten Commandments so that they can know the character of God. God is revealing the laws by which they can stay in relationship with their Lord who has rescued them. The fourth commandment is the longest of all the commandments given.
Remember the Sabbath day, to keep it holy. Six days you shall labor, and do all your work, but the seventh day is a Sabbath to the Lord your God. On it you shall not do any work, you, or your son, or your daughter, your male servant, or your female servant, or your livestock, or the sojourner who is within your gates. For in six days the Lord made heaven and earth, the sea, and all that is in them, and rested on the seventh day. Therefore the Lord blessed the Sabbath day and made it holy. (Exodus 20:8–11 ESV)
