Isaiah 56:2

For thus says Yahweh, “To the eunuchs who keep My sabbaths, And choose what pleases Me, And hold fast My covenant,

“Also the foreigners who join themselves to Yahweh, To minister to Him, and to love the name of Yahweh, To be His slaves, every one who keeps from profaning the sabbath And takes hold of My covenant,

“If because of the sabbath, you turn your foot From doing your own desire on My holy day, And call the sabbath a delight, the holy day of Yahweh honorable, And honor it, by not doing your own ways, By not finding your own desire And speaking your own word,

“You shall not bring a load out of your houses on the sabbath day nor do any work, but keep the sabbath day holy, as I commanded your fathers.
