'Humbling' in the Bible

Remember the whole way by which he has brought you these forty years through the desert so that he might, by humbling you, test you to see if you have it within you to keep his commandments or not.

fed you in the desert with manna (which your ancestors had never before known) so that he might by humbling you test you and eventually bring good to you.

Or did I commit a sin by humbling myself so that you could be exalted, because I proclaimed the gospel of God to you free of charge?
