Isaiah 66:14

And when ye see this - This great accession to the church from the Gentile world.

Your bones shall flourish like an herb - This is an image which is often employed in the Scriptures. When the vigor of the body fails, or when it is much afflicted, the bones are said to be feeble or weakened, or to be dried Psalms 6:2; Psalms 51:8; Psalms 22:14, Psalms 22:17; Psalms 38:3; Lamentations 1:13; Proverbs 14:30; Proverbs 17:22. like manner, prosperity, health, vigor, are denoted by making the bones fat (see the notes at Isaiah 58:11; Proverbs 15:20), or by imparting health, marrow, or strength to them Proverbs 3:8; Proverbs 16:24. The sense here is, that their vigor would be greatly increased.

The hand of the Lord shall be known - That is, it shall be seen that he is powerful to defend his people, and to punish their enemies.
