The Lord commands them to keep justice and do righteousness, for his salvation is about to come and his righteousness to be revealed. Blessed is the man who does this and keeps the Sabbath without profaning it, and keeps his hand from doing any evil. Verses 3 through 5 anticipate an objection: let not the foreigner who has joined himself to the Lord say that the Lord will separate him from his people, nor the eunuch say that he is a dry tree. To the eunuchs who keep his Sabbaths, choose what pleases him and hold fast his covenant, the Lord will give in his house and within his walls a monument and a name better than sons and daughters, an everlasting name that will not be cut off.
Verses 6 and 7 address the foreigners who join themselves to the Lord to minister to him, to love his name and to be his servants, all who keep the Sabbath without profaning it and hold fast his covenant. The Lord will bring them to his holy mountain and make them joyful in his house of prayer; their burnt offerings and sacrifices will be accepted on his altar, for his house will be called a house of prayer for all peoples. Verse 8 says that the Lord, who gathers the outcasts of Israel, will gather yet others besides those already gathered.
The second half changes tone. In verses 9 through 12 the Lord summons the beasts of the field and the forest to come and devour, because his watchmen are blind, all of them without knowledge; they are silent dogs that cannot bark, dreamers lying down, lovers of slumber. They are greedy dogs that never have enough, and shepherds without understanding. Each turns to his own way, each to his own gain. Come, they say, I will bring wine and we will drink our fill; tomorrow will be like today, or even greater.
