Isaiah 19:21

21 Then the Lord will be known to Egypt, and the Egyptians will know the Lord in that day, and will make sacrifice and offering; yes, they will make a vow to the Lord and perform it.

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 midst of the land of Egypt, and a pillar to the Lord at its border.

20 And it will be for a sign and for a witness to the Lord of hosts in the land of Egypt; for they will cry to the Lord because of the oppressors, and He will send them a Savior and a Mighty One, and He will deliver them.

21 Then the Lord will be known to Egypt, and the Egyptians will know the Lord in that day, and will make sacrifice and offering; yes, they will make a vow to the Lord and perform it.

22 And the Lord will strike Egypt, He will strike and heal it; they will return to the Lord, and He will be entreated by them and heal them.

23 In that day there will be a highway from Egypt to Assyria, and the Assyrian will come into Egypt and the Egyptian into Assyria, and the Egyptians will serve with the Assyrians.
