The Lord Intervenes In Our Lives
The Lord tells Moses and the Children of Israel to "camp by the sea." The Children of Israel are then concerned for their lives with nowhere to run from the Egyptians. The Lord then intervenes and has His prophet "divide the sea." The Lord works in the same manner in our own lives.
The Children of Israel "murmur" again and again regardless of knowing that the Lord is with them.
Amalek may be the origin of the Nephite dissident factions.
We all should sustain the prophet and hold up his arms.
