'Eat' in the Bible

Then all the people came and encouraged David to eat food while it was still day. But David took an oath saying, "God will punish me severely if I taste bread or anything whatsoever before the sun sets!"

You will cultivate the land for him -- you and your sons and your servants. You will bring its produce and it will be food for your master's grandson to eat. But Mephibosheth, your master's grandson, will be a regular guest at my table." (Now Ziba had fifteen sons and twenty servants.)

Uriah replied to David, "The ark and Israel and Judah reside in temporary shelters, and my lord Joab and my lord's soldiers are camping in the open field. Should I go to my house to eat and drink and have marital relations with my wife? As surely as you are alive, I will not do this thing!"

But the poor man had nothing except for a little lamb he had acquired. He raised it, and it grew up alongside him and his children. It used to eat his food, drink from his cup, and sleep in his arms. It was just like a daughter to him.

The elders of his house stood over him and tried to lift him from the ground, but he was unwilling, and refused to eat food with them.

Jonadab replied to him, "Lie down on your bed and pretend to be sick. When your father comes in to see you, say to him, 'Please let my sister Tamar come in so she can fix some food for me. Let her prepare the food in my sight so I can watch. Then I will eat from her hand.'"

So Amnon lay down and pretended to be sick. When the king came in to see him, Amnon said to the king, "Please let my sister Tamar come in so she can make a couple of cakes in my sight. Then I will eat from her hand."

But when she took the pan and set it before him, he refused to eat. Instead Amnon said, "Get everyone out of here!" So everyone left.

Then Amnon said to Tamar, "Bring the cakes into the bedroom; then I will eat from your hand." So Tamar took the cakes that she had prepared and brought them to her brother Amnon in the bedroom.

As she brought them to him to eat, he grabbed her and said to her, "Come on! Get in bed with me, my sister!"

The king asked Ziba, "Why did you bring these things?" Ziba replied, "The donkeys are for the king's family to ride on, the loaves of bread and the summer fruit are for the attendants to eat, and the wine is for those who get exhausted in the desert."

After all, there was no one in the entire house of my grandfather who did not deserve death from my lord the king. But instead you allowed me to eat at your own table! What further claim do I have to ask the king for anything?"

I am presently eighty years old. Am I able to discern good and bad? Can I taste what I eat and drink? Am I still able to hear the voices of male and female singers? Why should I continue to be a burden to my lord the king?
