Matthew Poole and continuators on 1 Kings 2:20

20 Then she said, I desire one small petition of thee, I pray thee say me not nay: and the king said unto her, Ask on, my mother, for I will not say thee nay .

So she esteemed it, because she did not perceive his Design in it; and as for that Law, Levit. 18. 7. the might apprehend, that because David knew her not, it was onely a Contract for Marriage, and therefore no impediment of her Marriage to any other after his Death; which also is the Opinion of some of the late Learned Hebrew Doctors.

Supposing thy Request be but small, as thou sayst it is, and not unlawful, nor injurious to my self, or others.
