Q 98 Where is the moral law summarily comprehended?

A.
The moral law is summarily comprehended in the ten commandments, which were delivered by the voice of God upon Mount Sinai, and written by him in two tables of stone;[420] and are recorded in the twentieth chapter of Exodus. The four first commandments containing our duty to God, and the other six our duty to man.[421]

[420] Deuteronomy 10:4. And he wrote on the tables, according to the first writing, the ten commandments, which the LORD spake unto you in the mount out of the midst of the fire in the day of the assembly: and the LORD gave them unto me.

Exodus 34:1-4. And the LORD said unto Moses, Hew thee two tables of stone like unto the first: and I will write upon these tables the words that were in the first tables, which thou brakest. And be ready in the morning, and come up in the morning unto mount Sinai, and present thyself there to me in the top of the mount. And no man shall come up with thee, neither let any man be seen throughout all the mount; neither let the flocks nor herds feed before that mount. And he hewed two tables of stone like unto the first; and Moses rose up early in the morning, and went up unto mount Sinai, as the LORD had commanded him, and took in his hand the two tables of stone.

[421] Matthew 22:37-40. Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second is like unto it, Thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets.
