“For you will be like a tree whose leaves wither, like an orchard that is unwatered.”
Isaiah’s imagery sees the wicked as trees who fail. This after mentioning the “sacred orchards” of idol worship. When the Lord judges, the unfaithful will not remain.
Contraste this image with Psa 1.3. In the present, and at the end, the righteous flourish. Which will you be?
