'Cause' in the Bible

For he took his life in his hand and struck the Philistine, and the Lord brought about a great deliverance for all Israel; you saw it and rejoiced. Why then will you sin against innocent blood by putting David to death without a cause?”

The Lord therefore be judge and decide between you and me; and may He see and plead my cause and deliver me from your hand.”

this will not cause grief or a troubled heart to my lord, both by having shed blood without cause and by my lord having avenged himself. When the Lord deals well with my lord, then remember your maidservant.”

When David heard that Nabal was dead, he said, “Blessed be the Lord, who has pleaded the cause of my reproach from the hand of Nabal and has kept back His servant from evil. The Lord has also returned the evildoing of Nabal on his own head.” Then David sent a proposal to Abigail, to take her as his wife.
