Adam Clarke on 1 Kings 3:16

Then came there two women - harlots - The word זנות zonoth, which we here, and in some other places, improperly translate harlots, is by the Chaldee (the best judge in this case) rendered פונדקין pundekayan, tavern-keepers. (See on Jos 2:1 (note)). If these had been harlots, it is not likely they would have dared to appear before Solomon; and if they had been common women, it is not likely they would have had children; nor is it likely that such persons would have been permitted under the reign of David. Though there is no mention of their husbands, it is probable they might have been at this time in other parts, following their necessary occupations; and the settling the present business could not have been delayed till their return; the appeal to justice must be made immediately.
