Yahowah's instructions reagrding the Sabbath are simple and straight forward, for 6 days you work and on the 7th you rest. Anyone trying to complicate it beyond that, like lunar sabbath proponents, are looking for something that isn't there.
I say look at what Yahowah's instruction was, word for word, and consider that. It doesn't matter what anyone else says.
Remember (zakar – recall, reflect upon, recognize, mark, memorialize, mention, proclaim, and be earnestly mindful of) that the Sabbath (shabat – the seventh day, the time of observance, of rest to reflect on God’s promise to settle our debts so we could settle with Him on the seventh) day (yowm) is set apart (qadash – is separated unto God for purifying and cleansing and thus special). Six (shesh) days you shall work (‘abad – labor) and do (‘asah – prepare and produce, fashion and finish, advance, assign, and accomplish, institute and celebrate) all (kol – the entirety of) your service of representing the Messenger and proclaiming the message (mala’kah – your Godly duties and heavenly labor). But the seventh (shaby’y – solemn promise which fulfills and satisfies those who listen and are observant of the role of the seventh) day (yowm), the Sabbath of (shabat – the seventh day, the time of observance, of rest and reflection, and of ceasing and desisting from ordinary labor to consider the promise to settle all disputes and settle down with) Yahowah (YHWH) your God (‘elohym), you shall not do (lo’ ‘asah – not prepare or produce, fashion or finish, advance, assign, or accomplish) any part of (kol) the work of God’s Representative and Messenger (mala’kah – from mal’ak, the ministry and mission of the heavenly envoy, the Divine endeavors and labor of God’s corporeal manifestation) yourself (‘atah), nor your son (ben), your daughter (bat), your servants and employees (‘ebed / ‘amah), your means of production (behemah – animals and beasts of burden), nor those visitors (ger – foreigners) who relationally (‘asher) are in your home, property, or community (sa’ar – area enclosed by a door or gate, a household, assembly, city, or nation). For indeed in (ky – because surely and truly in) six (shesh – symbolic of mankind being bleached white and purified) days (yowm) Yahowah (YaHoWaH) made (‘asah – prepared and produced, fashioned and finished, instituted and celebrated) accordingly (‘eth) the heavens (shamaym – the spiritual realm) and the earth (‘erets – the material world), and the seas (yam), and all (kol – everything) which relationally (‘asher) is in them (ba). And (wa) He became completely settled (nuwach – rested after settling all unresolved issues) during (ba) the seventh (shaby’y – solemn promise which fulfills and satisfies those who listen and are observant of the role of the seventh) day (yowm). Therefore (ken – consequently, this is true and correct) Yahowah blessed and adored (barak – knelt down and lowered Himself to greet those He had created and lift them up on) the Sabbath (shabat – the seventh day, the time of observance, of rest and reflection, and of ceasing and desisting from ordinary labor to consider the promise God has made to settle our debts and settle us in His home on this) day (yowm), setting it apart (qodesh – separating it from others, dedicating it to separation, cleansing, and purifying).
