Isaiah 19:21 Meaning and Commentary

Isaiah 19:21

And the Lord shall be known to Egypt
The means of knowing him would be granted them; which were partly through the Bible being translated into the Greek language, at the request of Ptolemy king of Egypt, which was then understood in that country, and this was a considerable time before the coming of Christ; and chiefly through the Gospel being brought hither by the Evangelist Mark, and others, whereby many of them were brought to a spiritual, experimental, and evangelical knowledge of Christ:

and the Egyptians shall know the Lord;
own and acknowledge him, profess faith in him, hope of happiness by him, love of him, and subjection to him, his Gospel and ordinances:

and shall do sacrifice and oblation;
not such sacrifice and oblation as were enjoined by the ceremonial law, since those would be now abrogated; but the spiritual sacrifices of prayer, praise, and good works, and of the presentation of themselves, as a holy, living, and acceptable sacrifice to God, their reasonable service: under these ceremonial rites is signified the whole spiritual worship of the New Testament:

yea, they shall vow a vow unto the Lord, and perform [it];
lay themselves under obligation to serve the Lord, and act according to it; see ( Ecclesiastes 5:4 Ecclesiastes 5:5 ) and this is to be understood not of legal vows, as that of the Nazarite, or any other, but of the spiritual one of praise and thanksgiving; see ( Psalms 50:14 ) ( 65:1 ) .

Isaiah 19:21 In-Context

19 In that day there will be an altar to the LORD in the heart of Egypt, and there will be a monument to the LORD at its border.

20 It will be a sign and a witness that the LORD of Heaven’s Armies is worshiped in the land of Egypt. When the people cry to the LORD for help against those who oppress them, he will send them a savior who will rescue them.

21 The LORD will make himself known to the Egyptians. Yes, they will know the LORD and will give their sacrifices and offerings to him. They will make a vow to the LORD and will keep it.

22 The LORD will strike Egypt, and then he will bring healing. For the Egyptians will turn to the LORD, and he will listen to their pleas and heal them.

23 In that day Egypt and Assyria will be connected by a highway. The Egyptians and Assyrians will move freely between their lands, and they will both worship God.
