The Lord will be known to Egypt, and the Egyptians will know the Lord in that day. Yes, they will worship with sacrifice and offering, and will make vows to the Lord, and will perform them.

KJV

And the LORD shall be known to Egypt, and the Egyptians shall know the LORD in that day, and shall do sacrifice and oblation; yea, they shall vow a vow unto the LORD, and perform it.

Commentary

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 Ecc 5:4 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 Psa 50:14 .
