'Humble' in the Bible

And you shall remember all [of] the way that Yahweh your God led you [during] these forty years in the desert in order to humble you and to test you to know what [is] in your heart, whether you would [diligently] keep his commandments or not.

the one {feeding you} manna in the desert, [food] that your ancestors did not know, in order to humble you and in order to test you [so that he could] do good to you {in the future}.
