'Intensify' in the Bible

He said to the woman:I will intensify your labor pains;you will bear children in anguish.Your desire will be for your husband,yet he will rule over you.

David told the messenger, “Say this to Joab: ‘Don’t let this matter upset you because the sword devours all alike. Intensify your fight against the city and demolish it.’ Encourage him.”

When I shoot deadly arrows of famine at them, arrows for destruction that I will send to destroy you, inhabitants of Jerusalem, I will intensify the famine against you and cut off your supply of bread.
