Isaiah 56:4

1 Thus saith the Lord: Keep ye judgment, and do justice: for my salvation is near to come, and my justice to be revealed.

2 Blessed is the man that doth this, and the son of man that shall lay hold on this: that keepeth the sabbath from profaning it, that keepeth his hands from doing any evil.

3 And let not the son of the stranger, that adhereth to the Lord, speak, saying: The Lord will divide and separate me from his people. And let not the eunuch say: Behold I am a dry tree.

4 For thus saith the Lord to the eunuchs, They that shall keep my sabbaths, and shall choose the things that please me, and shall hold fast my covenant:

5 I will give to them in my house, and within my walls, a place, and a name better than sons and daughters: I will give them an everlasting name which shall never perish.

6 And the children of the stranger that adhere to the Lord, to worship him, and to love his name, to be his servants: every one that keepeth the sabbath from profaning it, and that holdeth fast my covenant:

7 I will bring them into my holy mount, and will make them joyful in my house of prayer: their holocausts, and their victims shall please me upon my altar: for my house shall be called the house of prayer, for all nations.
