Charles Ellicott Commentary Isaiah 66:12

"For thus saith Jehovah, Behold, I will extend peace to her like a river, and the glory of the nations like an overflowing stream: and ye shall suck [thereof]; ye shall be borne upon the side, and shall be dandled upon the knees." — Isaiah 66:12 (ASV)

Ye shall be borne upon her sides. —Better, upon the side, or upon the knee, or hip. (See Note on Isaiah 60:4.) The outward figure is now presented as in an inverted form, to express a new spiritual fact. The children of Zion will find a maternal tenderness and care at the hands of the heathen nations, who are to be as their nursing mothers .
