Jeremiah 17:8

Shall not see when heat cometh. — Another reading, followed by the LXX. and Vulgate, gives shall not fear; there is, however, more force in the repetition of the same word as in Jeremiah 17:6. The man who trusts is like the strong tree, clothed with foliage, that “does not see,” i.e., does not regard or feel, the presence of the heat. Technically the meaning is the same in both cases, but in the latter case with the emphasised contrast of a parallelism. Fed by the stream that never fails, it “shall not be careful” or anxious about the scorching heat of summer. As the blasted heath sees no good, so the tree, in this case, sees no evil.
