Matthew Poole and continuators on Isaiah 30:2

2. That walk to go down into Egypt (and have not asked at my mouth ) to strengthen themselves in the strength of Pharaoh, and to trust in the shadow of Egypt.

That send Ambassadors to Egypt for succour, as we read, ver. 4. which the Iews were forward to do upon all occasions, and did now upon the Invasion of the King of Assyria, as is evident, from Isa. 20. 5, 6. and did the like against the King of Babylon, Ier. 37. 7. Ezek. 17. 15.

Either by the Priests or Prophets, as they were to do in weighty cases; of which, see Numb. 27. 21. Ios. 9. 14. 1 Sam. 23. 9, 10. 1 Kings 22. 7. Ier. 21. 2. and 42. 2, 20. or by studying my Word; which plainly directs them to another course, and forbids them this practice.

In their power (as it is in the foregoing Clause) and protection, which is oft signified by the shadow, as Iudg. 9. 15. Psal. 17. 8. and 91. 1, 4.
