Verse 4. - The eunuchs that... take hold of my covenant. The law of Deuteronomy 23:1 shall be abrogated under the new condition of things, for such as "take hold of God's covenant."

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, Joh 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.For thus saith the Lord unto the eunuchs that keep my sabbaths,.... That fear and serve the Lord; religiously observe all times of divine worship, and walk in all the commandments and ordinances of the Lord; show regard to all the institutions of the Gospel, and perform all religious exercises, private and public, on Lord's days, and at other times:

and choose the things that please me; who do that which is wellpleasing unto God, which he has declared in his word to be acceptable to him; and do that from right principles, with right views, and of choice; not forced to it by those who have authority over them, or led to it merely by example and custom:

and take hold of my covenant; not the covenant of circumcision, as Kimchi; for what had eunuchs to do with that? but the covenant of grace, the everlasting covenant, the covenant of peace before spoken of Isaiah 14:10, made between the Father and the Son, on account of the elect; which may be said to be taken hold of when a person by faith claims his interest in God as his covenant God; comes to Christ as the Mediator of the covenant; and deals with his blood, righteousness, and sacrifice, for pardon, justification, and atonement; regards all the promises and blessings of the covenant as belonging to him and lives by faith on them, as such; so David by faith laid hold on this covenant, 2 Samuel 23:5.
