to wait, to hope, to look expectantly for someone or something: a tense, leaning-forward expectation, most often directed toward God.
This is the great Hebrew word for hope, but it is not the soft, wishful kind. The picture behind it is a cord twisted tight and pulled taut. To wait in this sense is to be stretched between a present hardship and a promised future, holding on without letting go. It is an active posture of the whole person, not passive resignation, which is why the Psalms can pair it with the command to be strong and let your heart take courage.
Most often the one waited for is God himself. The person in distress turns toward him and stays turned, trusting that he will act because he has bound himself by promise. This is the steady drumbeat of the lament psalms, where the sufferer says again and again, I wait for you, and of the prophets, where Israel, and finally even the distant nations, look to God for rescue.
The same word covers a more ordinary kind of expectation: looking for a particular outcome, watching for it to arrive. Here the focus falls on the thing expected, and the Bible often turns the word bitter by showing the expectation dashed. A vineyard owner looks for good grapes and gets sour ones; a people look for peace and healing and find only terror; a sufferer looks for pity and finds none. The expectation is real and reasonable, which is exactly what makes its failure sting.
What holds these uses together is the forward lean of the word: the self stretched out toward something not yet in hand. When that something is God, the waiting becomes faith; when it is an outcome that fails, the same posture becomes the measure of the disappointment.
