'Nursing' in the Bible

I -- have I conceived all this people? I -- have I begotten it, that Thou sayest unto me, Carry it in thy bosom as the nursing father beareth the suckling, unto the ground which Thou hast sworn to its fathers?

And kings have been thy nursing fathers, And their princesses thy nursing mothers; Face to the earth -- they bow down to thee, And the dust of thy feet they lick up, And thou hast known that I am Jehovah, That those expecting Me are not ashamed.
