Matthew 5 chosen for today is probably the most quoted scripture chapter, even by people not knowing from whence the quotation originated. Then there are two chapters of Exodus.
Matthew 5 is about the sermon on the mount, and begins with the Beatitudes. After that Jesus added the spiritual dimension to the Law. He had not come to destroy the Law, but to fulfill the Law. Jesus first addressed murder, where vengeance is not for us to do, instead be reconciled with your adversary before you can be reconciled to God. Then He dealt with adultery, you are not only not to do it, you are not allowed to even think about it. Likewise, the only time divorce is allowed is for already committed adultery. Piling on, he addressed taking of oaths, this was serious business under the Law, but Jesus said “Let your yes be yes and your no, no”. Furthermore it was said “An eye for an eye” But Jesus told us to pray for our adversaries, no matter what, and love your enemies.
Exodus 15 tells of the songs of Moses and Miriam, as God had delivered them from the Egyptians. Then they arrived at the bitter waters of Marah and the sweet waters of Elim.
In Exodus 16 God gave them Manna (what is it?) and quail, and Moses gave the instructions on how to gather it. And they ate Manna for 40 years.
