391 I said, I will give attention to my ways, so that my tongue may do no wrong; I will keep my mouth under control, while the sinner is before me. 2 I made no sound, I said no word, even of good; and I was moved with sorrow. 3 My heart was burning in my breast; while I was deep in thought the fire was lighted; then I said with my tongue, 4 Lord, give me knowledge of my end, and of the measure of my days, so that I may see how feeble I am. 5 You have made my days no longer than a hand's measure; and my years are nothing in your eyes; truly, every man is but a breath. (Selah.) 6 Truly, every man goes on his way like an image; he is troubled for no purpose: he makes a great store of wealth, and has no knowledge of who will get it.

Commentary on Psalm 39:1-6
(Read Psalm 39:1-6)
If an evil thought should arise in the mind, suppress it. Watchfulness in the habit, is the bridle upon the head; watchfulness in acts, is the hand upon the bridle. When not able to separate from wicked men, we should remember they will watch our words, and turn them, if they can, to our disadvantage. Sometimes it may be necessary to keep silence, even from good words; but in general we are wrong when backward to engage in edifying discourse. Impatience is a sin that has its cause within ourselves, and that is, musing; and its ill effects upon ourselves, and that is no less than burning. In our greatest health and prosperity, every man is altogether vanity, he cannot live long; he may die soon. This is an undoubted truth, but we are very unwilling to believe it. Therefore let us pray that God would enlighten our minds by his Holy Spirit, and fill our hearts with his grace, that we may be ready for death every day and hour.
