Yesaya 19:19

19:19 At that time there will be an altar for the Lord in the middle of the land of Egypt, as well as a sacred pillar ¹  dedicated to the Lord at its border.

Yesaya 19:21

19:21 The Lord will reveal himself to the Egyptians, and they ²  will acknowledge the Lord’s authority ³  at that time. ⁴  They will present sacrifices and offerings; they will make vows to the Lord and fulfill them.

[19:19]  ¹ tn This word is sometimes used of a sacred pillar associated with pagan worship, but here it is associated with the worship of the Lord.

[19:21]  ² tn Heb “Egypt.” For stylistic reasons, to avoid redundancy, the present translation uses the pronoun (“they”) here.

[19:21]  ³ tn Heb “will know the Lord.”

[19:21]  ⁴ tn Heb “in that day” (so KJV), likewise at the beginning of vv. 23 and 24.
