'Needless' in the Bible

there will not be remorse or a troubled conscience for my lord because of needless bloodshed or my lord’s revenge. And when the Lord does good things for my lord, may you remember me your servant.”

Who has woe? Who has sorrow? Who has strife? Who has complaints? Who has needless bruises? Who has bloodshot eyes?

"And when praying, do not use needless repetitions as the Gentiles do, for they expect to be listened to because of their multitude of words.
