I asked this question on this post on a different instance, but would there be issues being that the code compares a float to integer zero “0”?

I’ve heard this as a reference to the bread that was given to the Israelites in the wilderness - manna. In Exodus, the Israelites are instructed to gather and prepare it each day. In the exegesis of that connection, I believe it is Jesus encouraging believers to trust in God for his provision daily.
