Isaiah 56:4 YLT

²  O the happiness of a man who doth this, And of a son of man who keepeth hold on it, Keeping the sabbath from polluting it, And keeping his hand from doing any evil.

³  Nor speak let a son of the stranger, Who is joined unto Jehovah, saying: 'Jehovah doth certainly separate me from His people.' Nor say let the eunuch, 'Lo, I am a tree dried up,'

⁴  For thus said Jehovah of the eunuchs, Who do keep My sabbaths, And have fixed on that which I desired, And are keeping hold on My covenant:

⁵  I have given to them in My house, And within My walls a station and a name, Better than sons and than daughters, A name age-during I give to him That is not cut off.

⁶  And sons of the stranger, who are joined to Jehovah, To serve Him, and to love the name of Jehovah, To be to Him for servants, Every keeper of the sabbath from polluting it, And those keeping hold on My covenant.
