'Side' in the Bible

Lift up round about thine eyes and see, All of them have been gathered, they have come to thee, Thy sons from afar do come, And thy daughters on the side are supported.

For thus said Jehovah: 'Lo, I am stretching out to her peace as a river, And as an overflowing stream the honour of nations, And ye have sucked, on the side ye are carried, And on the knees ye are dandled.
