3 And let not the man from a strange country, who has been joined to the Lord, say, The Lord will certainly put a division between me and his people: and let not the unsexed man say, See, I am a dry tree. 4 For the Lord says, As for the unsexed who keep my Sabbaths, and give their hearts to pleasing me, and keep their agreement with me: 5 I will give to them in my house, and inside my walls, a place and a name better than that of sons and daughters; I will give them an eternal name which will not be cut off. 6 And as for those from a strange country, who are joined to the Lord, to give worship to him and honour to his name, to be his servants, even everyone who keeps the Sabbath holy, and keeps his agreement with me: 7 I will make them come to my holy mountain, and will give them joy in my house of prayer; I will take pleasure in the burned offerings which they make on my altar: for my house will be named a house of prayer for all peoples. 8 The Lord God, who gets together the wandering ones of Israel, says, I will get together others in addition to those of Israel who have come back.

Matthew Henry's Commentary on Isaiah 56:3-8

Commentary on Isaiah 56:3-8

(Read Isaiah 56:3-8)

Unbelief often suggests things to discourage believers, against which God has expressly guarded. Spiritual blessings are unspeakably better than having sons and daughters; for children are a care, and may prove a grief and shame, but the blessings we partake of in God's house, are comforts which cannot be made bitter. Those who love the Lord truly, will serve him faithfully, and then his commandments are not grievous. Three things are promised. Assistance: I will not only bid them welcome, but incline them to come. Acceptance, and comfort: though they came mourning to the house of prayer, they shall go away rejoicing. They shall find ease by casting their cares and burdens upon God. Many a sorrowful spirit has been made joyful in the house of prayer. The Gentiles shall be one body with the Jews, that, as Christ says, John 10:16, there may be one fold and one Shepherd. Thanks be to God that none are separated from him except by wilful sin and unbelief; and if we come to him, we shall be accepted through the sacrifice of our great High Priest.
