'Pregnant' in the Bible

Then Hazael asked, "Why [is] my lord crying?" He said, "Because I know what evil you will do to the {Israelites}. You will {set their fortifications on fire}, and you will kill their young men with the sword. Their little ones you will dash to pieces, and their pregnant women you will rip open!"

At that time Menahem destroyed Tiphsah, all who [were] in it, and all its territory from Tirzah, because [it] had not opened [to him], so he destroyed it and ripped open all of its pregnant women.
