Exodus 34:26-28 21st Century King James Version (KJ21)
26 The first of the firstfruits of thy land thou shalt bring unto the house of the Lord thy God. Thou shalt not boil a kid in his mother’s milk.”
27 And the Lord said unto Moses, “Write thou these words, for according to the tenor of these words I have made a covenant with thee and with Israel.”
28 And he was there with the Lord forty days and forty nights; he neither ate bread nor drank water. And He wrote upon the tablets the words of the covenant, the Ten Commandments.
