Psalms 34:15

The eyes of the Lord are upon the righteous - This is another of the ways in which the psalmist says that life will be lengthened out, or that those who desire life may find it. The Lord will be the protector of the righteous; he will watch over and defend them. See the notes at Job 36:7.

And his ears are open unto their cry - That is, when in trouble and in danger. He will hear them, and will deliver them. All this seems to be stated as the result of the experience of the psalmist himself; He had found that the eyes of God had been upon him in his dangers, and that His ears had been open when he called upon Him Psalms 34:6; and now, from his own experience, he assures others that the way to secure life and to find prosperity is to pursue such a course as will ensure the favor and protection of God. The general thought is, that virtue and religion - the love of truth, and the love of peace - the favor and friendship of God, will tend to lengthen out life, and to make it prosperous and happy. All the statements in the Bible concur in this, and all the experience of man goes to confirm it.
