Psalms 62:9-10

It is unwise to put one’s ultimate confidence in other people, whether they are of low or high position. The reason for this is that all human beings are comparatively insignificant. They are as transitory and ephemeral as a breath of wind (lit. vapor; cf. Psalms 39:5; Psalms 39:11; Psalms 144:4; Ecclesiastes 12:1; Ecclesiastes 12:7). Consequently the actions and products of human endeavor are poor objects in which to trust.

"The point, then, is not so much that we have nothing to fear from man (as in Psalms 27:1 ff.), as that we have nothing to hope from him." [Note: Kidner, p. 223.]
