3 Let not the foreigner say, who has attached himself to the Lord, "The Lord will keep me apart from His people"; And let not the eunuch say, "I am a withered tress"
4 For thus said the Lord, "As for the eunuchs who kept my sabbaths, who have chosen what I desire, and hold fast to My covenant --
5 I will give them, in My House,
And within My walls,
A monument and a name
Better than sons or daughters.
I will give them an everlasting name which shall not perish.
6. As for the foreigners,
Who attach themselves to the Lord,
To minister to Him,
And to love the name of the Lord,
To be His servants --
All who keep the Sabbath and do not profrain it,
And who hold fast to My covenant --
7 I will bring them to My sacred mount
And let them rejoice in My house of prayer.
Their burnt offerings & sacrifices
Shall be welcome in My altar;
For My House shall be called
A house of prayer for all peoples".
8 Thus declared the Lord God, who gathers the dispersed of Israel:
"I will gather still more to those already gathered"
