'Strange' in the Bible

They have been false to the Lord; they have given birth to strange children; now the new moon will make them waste with their fields.

For they have been planting the wind, and their fruit will be the storm; his grain has no stem, it will give no meal, and if it does, a strange nation will take it.

Though I put my law in writing for him in ten thousand rules, they are to him as a strange thing.
