This was a tree to be envied. Growing on riverfront property, it didn’t have to worry about weather reports, withering temperatures, or an uncertain future. Nourished and cooled by the river, it spent its days lifting its branches to the sun, holding the earth with its roots, cleaning the air with its leaves, and offering shade to all who needed refuge from the sun.
By contrast, the prophet Jeremiah pointed to a shrub (Jer. 17:6). When the rains stopped and the summer sun turned the ground to dust, the bush shriveled into itself, offering no shade or fruit to anyone.
Why would the prophet compare a flourishing tree to a withering bush? He wanted his people to recall what had happened since their miraculous rescue from the slave yards of Egypt. For forty years in a wilderness, they lived like a tree planted by a river (Jer. 2:4–6). Yet in the prosperity of their promised land they had forgotten their own story; they were relying on themselves and on gods of their own making (vv. 7–8), even to the point of going back to Egypt looking for help (42:14).
So God, through Jeremiah, lovingly urged the forgetful children of Israel, and us, to be like the tree—not the bush.
