Wisdom 9:14

14 For the thoughts of mortal men are miserable, and our devices are but uncertain.

Wisdom 9:14 In-Context

12 So shall my works be acceptable, and then shall I judge thy people righteously, and be worthy to sit in my father's seat.
13 For what man is he that can know the counsel of God? or who can think what the will of the Lord is?
14 For the thoughts of mortal men are miserable, and our devices are but uncertain.
15 For the corruptible body presseth down the soul, and the earthy tabernacle weigheth down the mind that museth upon many things.
16 And hardly do we guess aright at things that are upon earth, and with labour do we find the things that are before us: but the things that are in heaven who hath searched out?
