REMEMBER THE SABBATH

Thus the heavens and the earth were finished; and all the host of them. And on the seventh day God ended His work which He had made; and He rested on the seventh day from all His work which had made. And God blessed the seventh day and sanctified it: because that in it He had rested form all is work which God created and made. Gen.2:1-3

God was the first being to keep the Sabbath.

Remember the Sabbath day, to keep it holy. Six days you shall labor and do all your work: but the seventh day is the Sabbath of YHVH your God: in it you shall not do any work, you, nor your son, nor your daughter, nor the stranger that is within your gates: for in six days YHVH made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore YHVH blessed the Sabbath day, and set it apart. (Ex. 20:8-11)
Did you know: This is one of the ten commandments

What shouldn't you do on the Sabbath?
You shall kindle no fire throughout your habitations on the sabbath day. (Ex. 35:3)

Thus says YHVH: “Take heed to yourselves, and bear no burden on the Sabbath day, nor bring it in by the gates of Jerusalem; nor carry a burden out of your houses on the Sabbath day, nor do any work, but hallow the Sabbath day, as I commanded your fathers. (Jeremiah 17:21-22)

For YHVH has given you the Sabbath; therefore He gives you on the sixth day bread for two days. Let every man remain in his place; let no man go out of his place on the seventh day. (Exodus 16:29)

If the people of the land bring merchandise or food to sell on the Sabbath, we should not buy from them on the Sabbath or on a holy day. (Nehemiah 10:31)

If you hold back your foot on the Sabbath from pursuing your own interests on My holy day; if you call the Sabbath a delight, YHVH's holy day, worth honoring; then honor it by not doing your usual things or pursuing your interests or speaking about them. If you do, you will find delight in YHVH. (Isaiah 58:13)

Who should keep the Sabbath?
Thus says YHVH, “Observe justice, do what is right , for my salvation is close to coming, my righteousness to being revealed.” Happy is the person who does this, anyone who grasps it firmly, who keeps the Sabbath and does not profane it, and keeps himself from evil.
A foreigner [non-Jew] joining to YHVH should not say, “YHVH will separate me from his people.” likewise the eunuch should not say, “I am only a dried-up tree.”
For here is what YHVH says: “As for the eunuchs who keep my Sabbaths, who choose what pleases me and hold fast to my covenant: in my house, within my walls,I will give them power and a name greater than sons and daughters; I will give him an everlasting name that will no be cut off.
“And the foreigners [non-Jews]who join themselves to YHVH to serve him, to love the Name of YHVH and to be his workers, all who keep the Sabbath and do not profane it, and hold fast to my covenant, I will bring them to my holy mountain and make them joyful in my house of prayer; their burnt offerings and sacrifices will be accepted on my altar; for my house will be called a house of prayer for all peoples.” (Is. 56:1-7)
When is it ok to work on the Sabbath?
And he saith unto them, Is it lawful to do good on the sabbath days, or to do evil? to save life, or to kill? But they held their peace. (Mark 3:4)

And the ruler of the synagogue answered with indignation, because that Jesus had healed on the sabbath day, and said unto the people, There are six days in which men ought to work: in them therefore come and be healed, and not on the sabbath day. The Lord then answered him, and said, Thou hypocrite, doth not each one of you on the sabbath loose his ox or his ass from the stall, and lead him away to watering? (Luke 13:14-15)

And answered them, saying, Which of you shall have an ass or an ox fallen into a pit, and will not straightway pull him out on the sabbath day? Luke 14:5
