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 shall there be an altar to the LORD in the midst of the land of Mitzrayim, and a pillar at the border of it to the LORD.

20 It shall be for a sign and for a witness to the LORD of Hosts in the land of Mitzrayim; for they shall cry to the LORD because of oppressors, and he will send them a savior, and a defender, and he will deliver them.

21 The LORD shall be known to Mitzrayim, and the Mitzrim shall know the LORD in that day; yes, they shall worship with sacrifice and offering, and shall vow a vow to the LORD, and shall perform it.

22 The LORD will strike Mitzrayim, smiting and healing; and they shall return to the LORD, and he will be entreated of them, and will heal them.

23 In that day shall there be a highway out of Mitzrayim to Ashshur, and the Ashshur shall come into Mitzrayim, and the Mitzrian into Ashshur; and the Mitzrim shall worship with the Ashshur.
