'Slack' in the Bible

We have heard news of it, our hands grow slack, anxiety has grasped us, pain as a [woman who] gives birth.

Then the officials said to the king, "Please, this man must be killed, {because} he [is] making slack the hands of {the soldiers} who are left in this city, and the hands of all the people, by speaking to them words like these, for this man [is] not seeking for welfare to this people, {but only} for harm."

Damascus has grown slack. She has turned away to flee and panic. Anxiety has seized [her], and labor pains have grasped her, like a woman in labor.

The king of Babylon heard their report and his hands grew slack. Anxiety has seized him, fear and pain like the [woman who] gives birth.
