'Low' in the Bible

And a leper approached, and bowed low before him, saying, "Lord, if you are willing, you can make me clean."

As he was saying these things, a ruler came, bowed low before him, and said, "My daughter has just died, but come and lay your hand on her and she will live."

Every valley will be filled, and every mountain and hill will be brought low, and the crooked will be made straight, and the rough ways will be made smooth,

God chose what is low and despised in the world, what is regarded as nothing, to set aside what is regarded as something,
