Leviticus 23:2-3 (NKJV)
[SUP]2 [/SUP] "Speak to the children of Israel, and say to them: 'The feasts of the LORD, which you shall proclaim to be holy convocations, these are My feasts.
[SUP]3 [/SUP] 'Six days shall work be done, but the seventh day is a Sabbath of solemn rest, a holy convocation. You shall do no work on it; it is the Sabbath of the LORD in all your dwellings.
For who?
Exodus 31:13 (HCSB)
[SUP]13 [/SUP]“Tell the Israelites: You must observe My Sabbaths, for it is a sign between Me and you throughout your generations, so that you will know that I am Yahweh who sets you apart.
AND then in the New Testament the Priesthood Changed from the Tribe of Levi to the Tribe of Judah:
Hebrews 7:12 (NASB)
[SUP]12 [/SUP]For when the priesthood is changed, of necessity there takes place a change of law also.
Hebrews 10:24-25 (NKJV)
[SUP]24 [/SUP]And let us consider one another in order to stir up love and good works,
[SUP]25 [/SUP]not forsaking the assembling of ourselves together { no mention of the day }, as is the manner of some, but exhorting one another, and so much the more as you see the Day approaching.
Romans 14:5 (NKJV)
[SUP]5 [/SUP]One person esteems one day above another; another esteems every day alike. Let each be fully convinced in his own mind.
It appears we have nothing to debate on this subject.
