In Genesis 8:21, this signifies that worship from charity and the faith of charity pleased the Lord. (Arcana Coelestia 924-925)

In Exodus 15:25, this signifies that truths became enjoyable. (Arcana Coelestia 8356)

'Sweet' signifies delightful things from the good of truth and the truth of good. Everything sweet in the natural world corresponds to delightful and pleasant things in the spiritual world.

7838. 'A male' means which is characteristic of faith rooted in charity. This is clear from the meaning of 'a male' as the truth of faith, dealt with in 2046, 4005, and so faith rooted in charity, since the truth of faith is not the truth of faith unless it exists together with the good of charity, and springs from that good most of all. The reason why the Passover animal had to be a male was that that animal was a sign of the innocence of those belonging to the spiritual Church. And those belonging to the spiritual Church possess no other kind of good than that which is in itself the truth of faith; for this is called good when from charitable affection it is put into action, 7835. This is why it had to be a male animal. At other times female animals were also used in sacrifices, when worship springing from good was to be represented.
