To the choirmaster. A Psalm of David.
Psalm 139 Revised Standard Version

O Lord, thou hast searched me and known me!
Thou knowest when I sit down and when I rise up;
    thou discernest my thoughts from afar.
Thou searchest out my path and my lying down,
    and art acquainted with all my ways.
Even before a word is on my tongue,
    lo, O Lord, thou knowest it altogether.
Thou dost beset me behind and before,
    and layest thy hand upon me.
Such knowledge is too wonderful for me;
    it is high, I cannot attain it.

Whither shall I go from thy Spirit?
    Or whither shall I flee from thy presence?
If I ascend to heaven, thou art there!
    If I make my bed in Sheol, thou art there!
If I take the wings of the morning
    and dwell in the uttermost parts of the sea,
even there thy hand shall lead me,
    and thy right hand shall hold me.
If I say, “Let only darkness cover me,
    and the light about me be night,”
even the darkness is not dark to thee,
    the night is bright as the day;
    for darkness is as light with thee.

For thou didst form my inward parts,
    thou didst knit me together in my mother’s womb.
I praise thee, for thou art fearful and wonderful.
    Wonderful are thy works!
Thou knowest me right well;
    my frame was not hidden from thee,
when I was being made in secret,
    intricately wrought in the depths of the earth.
Thy eyes beheld my unformed substance;
    in thy book were written, every one of them,
the days that were formed for me,
    when as yet there was none of them.
How precious to me are thy thoughts, O God!
    How vast is the sum of them!
If I would count them, they are more than the sand.
    When I awake, I am still with thee.

O that thou wouldst slay the wicked, O God,
    and that men of blood would depart from me,
men who maliciously defy thee,
    who lift themselves up against thee for evil!
Do I not hate them that hate thee, O Lord?
    And do I not loathe them that rise up against thee?
I hate them with perfect hatred;
    I count them my enemies.
Search me, O God, and know my heart!
    Try me and know my thoughts!
And see if there be any wicked way in me,
    and lead me in the way everlasting!
