'Worry' in the Bible

The tribe of Zebulun did not worry about their lives at the price of death; neither did the tribe of Naphtali also on high places of the field.

When their fathers or brothers come and protest to us, we'll say to them, "Do us a favor and let them be, for we could not get each one a wife through battle. Don't worry about breaking your oath! You would only be guilty if you had voluntarily given them wives.'"
