2:11-13
It is stressed that the grain offerings were to be made without yeast. This was a reminder of the deliverance from captivity in Egypt. It was also to be made without honey. It is not clear why honey was to be excluded. However, a possible interpretation of the absence of honey and yeast is that the gifts were not to be elaborate, in which case the focus can start to be on the gift and on what we can do for God. Instead the emphasis was to be on what God had done for them in setting them free from Egypt. Conversely, salt was to be added. Possibly because of salt’s preservative properties?
2:14-16
Offering the first fruits to the Lord is a common feature of true worship of the Lord, knowing that we are completely dependent upon Him, and so giving our first and best to Him. The crushed heads of new grain is perhaps looking forward to entering the Promised Land, when the grain would replace the manna.
