For your shame ye shall have double: See Poole on "Isaiah 40:2". Supply honour. Though you have been little accounted of among your enemies, yet now you shall be greatly in their esteem, Malachi 9:12; you shall have double damages. In their portion, viz. of honour that God will give them; the same thing with the former: or, in their inheritance which God shall restore to them; and that either, 1. For worth and value through God's blessing upon it. Or,
2. For room and space, and that possibly by reason of the few that will return to inhabit there, viz. only a tenth part, Isaiah 6:13; or that which he shall give them out of their enemy's land. Therefore; or rather, because; being rendered as a reason of their rejoicing, because of the doubling of their portion, in which sense it is taken Isaiah 16:14. Everlasting joy; of long continuance here, and everlasting hereafter; or to be perpetually remembered on their anniversary festivals: though this had its accomplishment in their return from Babylon, yet was it most signally made good in that great change for the better which they should find in the gospel state, in the enlargement of Christ's kingdom and increase of his people, with whom they should ever rejoice together.
