After the main body of Israelites showed their lack of faith (see Numbers 13–14) and sinned against the Lord, it is not surprising that Numbers 15 speaks about sacrificial offerings necessary for forgiveness of sins. Numbers 15 specifically speaks of sinning “presumptuously,” which means to sin knowing that what you are doing is wrong (compare Numbers 14:44 with Numbers 15:30–31). Numbers 15 closes with a commandment that could help Israel always remember the importance of obeying the commandments.
