sir82, that is a good question. I did not mean that the exact wording was applied to YHWH in the OT, only that YHWH was the only Lord ever to have been said to be over the Sabbath, the creator of the Sabbath, and to whom the Sabbath was dedicated. All of a sudden Jesus is claiming HE is the one who created the Sabbath and that He is the Lord to whom the Sabbath is dedicated.
but the seventh day is a sabbath of the LORD [YHWH] your God ; in it you shall not do any work, you or your son or your daughter, your male or your female servant or your cattle or your sojourner who stays with you. (Exodus 20:10)
then he said to them, "This is what the LORD [YHWH] meant: Tomorrow is a sabbath observance, a holy sabbath to the LORD . Bake what you will bake and boil what you will boil, and all that is left over put aside to be kept until morning." (Exodus 16:23)
Moses said, "Eat it today, for today is a sabbath to the LORD [YHWH]; today you will not find it in the field. (Exodus 16:25)
If Jesus did not mean to say that He was that same Lord over the Sabbath then what did He mean by calling Himself the Lord of the Sabbath?
