'Sabbath' in the Bible

You must not {continue} to bring offerings of futility, incense--it [is] an abomination to me; new moon and Sabbath, [the] calling of a convocation-- I cannot endure iniquity with [solemn] assembly.

Happy [is the] man [who] does this, and [the] son of humankind [who] keeps hold of it, who keeps [the] Sabbath {so as not to profane} it, and who keeps his hand from doing any evil."

And the {foreigners} [who] join themselves to Yahweh to serve him and to love the name of Yahweh, to become his servants, every one who keeps [the] Sabbath, {so as not to profane} it, and those who keep hold of my covenant,

If you hold your foot back from [the] Sabbath, [from] doing your affairs on {my holy day}, if you call the Sabbath a pleasure, the holy [day] of Yahweh honorable, if you honor him {more than} doing your ways, than finding your affairs and speaking a word,

And this shall happen: From {new moon to new moon} and from {Sabbath to Sabbath} all flesh shall come to bow in worship before me," says Yahweh.
