Travels through Exodus . . . part two

Exodus 12:2 . . .
After all of these plagues, God starts everything anew by beginning a new calendar year. This symbolizes the importance of the Passover. This also reflects the beginning of a new calendar after Jesus died.

Exodus 12:32 . . .
"'Take your flocks and herds, as you said, and be gone. Go, but bless me as you leave.'"
Amazingly, Pharaoh asks Moses to bless him after all of this destruction he had caused. What gall!! There is no mention is Moses does so.

Exodus 13:9 . . .
"'With a strong hand, the Lord rescued you from Egypt.'"

Exodus 14:10-14 . . .
Already the people begin to panic and complain. Where is their trust in the Lord? He performed multiple miracles and was with them day and night in the pillar of cloud/fire. Where was their belief? Where is mine knowing all they knew—and more?

Exodus 14:15-31 . . .
What must Moses have felt as he obeyed God while knowing that by doing so he was helping to send the Egyptians to their deaths? What must it have felt like to watch God save your people through yet another miracle and then watch your enemies be swallowed by the sea and washed up on shore?

Exodus 15:1-21 . . .
The Hebrews sing a song of celebration about their deliverance from the Egyptians. Does this seem odd to anyone? It's almost amazing that there could be such a celebration after witnessing the downfall of Egypt through the suffering of the plagues and destruction of Pharaoh and his army. Is it wrong to celebrate death and destruction? Or did they celebrate God's righteous judgment, which makes it all right?
