Isaiah 56:2, 6

“Blessed (happy, fortunate) is the man who does this, And the son of man who takes hold of it, Who keeps the Sabbath without profaning it, And keeps his hand from doing any evil.”

¶“Also the foreigners who join themselves to the LORD, To minister to Him, and to love the name of the LORD, To be His servants, everyone who keeps the Sabbath without profaning it And holds fast to My covenant [by conscientious obedience]
