Actually...it is in the New Testament...and in the Gospels.
Here:
"Do not think that I have come to abolish the law and the prophets. I have come, not to abolish them, but to fulfill them. Of this much I assure you; UNTIL HEAVEN AND EARTH PASS AWAY, not the smallest letter of the law, not the smallest part of a letter shall be done away with until it all comes true."
Matthew 5:17ff
Finally something that we can agree on Frank.
Exodus 20:
3 “You shall have no other gods before Me.
4 “You shall not make for yourself a carved image—any likeness
of anything that
is in heaven above, or that
is in the earth beneath, or that
is in the water under the earth; 5 you shall not bow down to them nor serve them. For I, the Lord your God,
am a jealous God, visiting the iniquity of the fathers upon the children to the third and fourth
generations of those who hate Me, 6 but showing mercy to thousands, to those who love Me and keep My commandments.
7 “You shall not take the name of the Lord your God in vain, for the Lord will not hold
him guiltless who takes His name in vain.
8 “Remember the Sabbath day, to keep it holy. 9 Six days you shall labor and do all your work, 10 but
the seventh day is the Sabbath of the Lord your God. In it you shall do no work: you, nor your son, nor your daughter, nor your male servant, nor your female servant, nor your cattle, nor your stranger who
is within your gates. 11 For
in six days the Lord made the heavens and the earth, the sea, and all that
is in them, and
rested the seventh day. Therefore the Lord blessed the Sabbath day and hallowed it.
