 How did you know that? I only read it once. That's exactly what he says in this text in verse 10. He ends up saying, and he said to them, go eat. In other words, take lunch. He says, for this day is the Lord. Do not be grieved for the joy of the Lord. The joy of Yahweh is what gives you strength to carry on. You shall mount up with wings as eagles. You shall run and not be weary. You shall walk and not faint. Who said that? Some old guy named Isaiah. Yeah.
