'Something' in the Bible

In the meanwhile the disciples were asking him, saying, "Rabbi, eat [something]!"

After these [things] Jesus found him at the temple and said to him, "Look, you have become well! Sin no longer, lest something worse happen to you."

But some of them said, "Was not this man who opened the eyes of the blind able to do [something] so that this man also would not have died?"

For some were thinking because Judas had the money box, Jesus was telling him, "Purchase {what we need} for the feast," or that he should give something to the poor.)
