'Speak' in the Bible

So Eli said to Samuel, “Go, lie down, and it shall be that if He calls you, you shall say, ‘Speak, Lord, for Your servant is listening.’” So Samuel went and lay down in his place.

Then the Lord came and stood and called as at the previous times, “Samuel! Samuel!” Then Samuel answered, “Speak, for Your servant is listening.”

Saul replied, “Am I not a Benjamite, of the smallest of the tribes of Israel? And is not my family the smallest of all the families of the tribe of Benjamin? Why then have you spoken this way to me [as if I were very important]?”

Then Saul commanded his servants, “Speak to David secretly, saying, ‘Listen, the king delights in you, and all his servants love you; now then, become the king’s son-in-law.’”

Now then, know this and consider what you should do, for evil is [already] planned against our master and against all his household; but he is such a worthless and wicked man that one cannot speak [reasonably] to him.”

Kneeling at his feet she said, “My lord, let the blame and guilt be on me alone. And please let your maidservant speak to you, and listen to the words of your maidservant.
