Westminster Q98: Where is the moral law summarily comprehended?

A98: 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;[1] 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.[2]

(Deu 10:4) "He wrote on the tablets, like the former writing, the Ten Commandments which the LORD had spoken to you on the mountain from the midst of the fire on the day of the assembly; and the LORD gave them to me.

(Exo 34:1-4) Now the LORD said to Moses, "Cut out for yourself two stone tablets like the former ones, and I will write on the tablets the words that were on the former tablets which you shattered. "So be ready by morning, and come up in the morning to Mount Sinai, and present yourself there to Me on the top of the mountain. "No man is to come up with you, nor let any man be seen anywhere on the mountain; even the flocks and the herds may not graze in front of that mountain." So he cut out two stone tablets like the former ones, and Moses rose up early in the morning and went up to Mount Sinai, as the LORD had commanded him, and he took two stone tablets in his hand.
(Mat 22:37-40) And He said to him, " 'YOU SHALL LOVE THE LORD YOUR GOD WITH ALL YOUR HEART, AND WITH ALL YOUR SOUL, AND WITH ALL YOUR MIND.' "This is the great and foremost commandment. "The second is like it, 'YOU SHALL LOVE YOUR NEIGHBOR AS YOURSELF.' "On these two commandments depend the whole Law and the Prophets."
