Observe the perfect, and see the upright, For the latter end of each is peace.

To the Overseer, to Jeduthun. -- A Psalm of David. I have said, 'I observe my ways, Against sinning with my tongue, I keep for my mouth a curb, while the wicked is before me.'

That they may observe His statutes, And His laws may keep. Praise ye Jehovah!

Beth. With what doth a young man purify his path? To observe -- according to Thy word.

Cause me to understand, and I keep Thy law, And observe it with the whole heart.

Ransom me from the oppression of man, And I observe Thy precepts,

If iniquities Thou dost observe, O Lord, who doth stand?
