Isaiah 56: come foreigners and castrated men!

 In Isaiah 56:1-8, the Lord calls foreigners and castrated men to join the people of the Lord.

3 Foreigners who have joined Yahweh should not say, “Yahweh will separate us from his people.” Castrated men should not say, “We’re only dead trees!”

 4 This is what Yahweh says: I will remember the castrated men who keep my days of worship, choose what pleases me, and faithfully observe the conditions of my promise.[a] 5 Inside my house and within my walls, I will give them something better than sons and daughters. I will give them a monument and a name. I will give them a permanent name that will not be forgotten. 6 And I will remember the foreigners who have joined Yahweh to worship him, to love Yahweh’s name, and to be his servants. All of them will keep the day of worship from becoming unholy and will faithfully observe the conditions of my promise. 7 Then I will bring them to my holy mountain and make them happy in my house of prayer. Their burnt offerings and their sacrifices will be acceptable on my altar, because my house will be called a house of prayer for all nations.

 The Lord wants that the foreigner and thre castrated men adores Him inside the community, together, in the day of worship. The Lord promises that He will make them happy in his house of prayer. Besides them, there are others that the Lord will gather:

 8 Adonay Yahweh, who gathers the scattered people of Israel, declares, “I will gather still others besides those I have already gathered.”

 In Isaiah 56:9-12, the Lord is against Israel’s watchmen. They should watch, but they don't, instead they are taking care of themselves. It reminds Jesus discourses against hypocrisy.
