"
and in which commandment?" Here we go again. Are you suggesting that there was an editing change on the second set of tablets?
The second set of tablets were cut by Moses and then rewritten by God (Exodus 34:1-29). The Lord then gave Moses further instructions to write down and read to the people.
27 Then the Lord said to Moses, Write these words, for according to the tenor of these words I have made a covenant with you and with Israel. 28 So he was there with the Lord forty days and forty nights; he neither ate bread nor drank water. And He wrote on the tablets the words of the covenant, the Ten Commandments. (NKJV)
Rabbis teach that the first five sayings, on the left tablet, concern man's relationship with God (belief in God, prohibition of improper worship, prohibition of oath, shabbat, respect for parents). The second five sayings, on the right tablet, concern man's relationship with other people (prohibitions of murder, adultery, theft, false witness, coveting).
Judaism teaches that our relationship to our parents is akin to our relationship to God because our parents created us. Disrespect of parents is considered an insult to God. Thus, respect for parents is included on the right side of the tablets with the other sayings that concern our relationship with God. Judaism teaches that the two tablets are parallel. In other words, our duties to God and our duties to people are equally important.
