Mark 13:17

But woe to them that are with child
Who because of their burdens, would be very unfit for, and very incapable of fleeing with any haste; and therefore very liable to fall into the hands of the enemy, and become their prey:

and to them that give suck in those days;
who could not bear to leave their children behind, and yet would not be able to carry them with them; at least not without great trouble, and which would much retard their flight, and endanger their being taken by the enemy; (See Gill on Matthew 24:19).
