'Speak' in the Bible

Therefore Eli said unto Samuel, Go, lie down: and it shall be, if he call thee, that thou shalt say, Speak, LORD; for thy servant heareth. So Samuel went and lay down in his place.

And the LORD came, and stood, and called as at other times, Samuel, Samuel. Then Samuel answered, Speak; for thy servant heareth.

Now therefore know and consider what thou wilt do; for evil is determined against our master, and against all his household: for he is such a son of Belial, that a man cannot speak to him.

And fell at his feet, and said, Upon me, my lord, upon me let this iniquity be: and let thine handmaid, I pray thee, speak in thine audience, and hear the words of thine handmaid.
