'Sabbath' in the Bible

Happy is the man who does this,anyone who maintains this,who keeps the Sabbath without desecrating it,and keeps his hand from doing any evil.

And the foreigners who join themselves to the Lordminister to Him, love the name of Yahwehand become His servants,all who keep the Sabbath without desecrating itand who hold firmly to My covenant—

“If you keep from desecrating the Sabbath,from doing whatever you want on My holy day;if you call the Sabbath a delight,and the holy day of the Lord honorable;if you honor it, not going your own ways,seeking your own pleasure, or talking too much;

All mankind will come to worship Mefrom one New Moon to anotherand from one Sabbath to another,”says the Lord.
