'Merely' in the Bible

So Saul said, "Tell me what you have done." So Jonathan told him and said, "I {merely tasted} a little honey with the end of the staff that was in my hand. Here I am, I must die."

David replied, "What have I done now? {I merely asked a question}!

Then David {took an oath} again and said, "Your father knows very well that I have found favor in your eyes, and he thought, 'Do not let Jonathan know this, lest he worry.' But {as Yahweh lives} and {as your soul lives}, surely [there is] merely a step between me and death!"
