Even though the present generation of Israelites would not be allowed to enter the Promised Land, God continued to enact laws that would govern the people who would eventually inhabit the land. Some of those laws dealt with the various offerings made by the people.
As careful as one may be to observe the laws of God, there are instances when sins are committed unintentionally. God recognized that weakness of man and made provisions for unintentional sins to be atoned. Intentional or presumptuous sins are a more serious matter. They come from a rebellious heart and will be dealt with more severely.
“Remember the Sabbath Day to keep it holy,” demanded utmost respect from the Israelites. A person who had gathered sticks on the Sabbath day was stoned to death for his deed.
A method of remembering to do a task is to tie a string around one’s finger. God required the Israelites to make tassels on the corners of their garments as a reminder of His commandments to them. Christians use unleavened bread and fruit of the vine as a memorial to remind them of the death, burial and resurrection of Christ.
