Of David.

1 Vindicate me, O LORD,
for I have led a blameless life;
I have trusted in the LORD
without wavering.
2 Test me, O LORD, and try me,
examine my heart and my mind;
3 for your love is ever before me,
and I walk continually in your truth.

Your love is ever before me – Or, ‘Your lovingkindness is before my eyes’.  ‘Keeping God’s love before our eyes is, besides an intellectual matter, a great encouragement to us, for how often shall we need this!  We shall feel our lack of it under a sense of our guilt, unworthiness, and continued imperfections.  Nothing short of the exceeding riches of His grace in His kindness toward us by Jesus Christ will be able to relieve us – and this will relieve us, and effectually, too!  It will give us everlasting consolation and good hope through grace, and boldness and access, with confidence, by the faith of Him.  And it will do all this without reconciling us to our sins or even our infirmities – yes, it will make us lament our deficiencies the more, grieving that we serve Him so little who loves us so much.  We shall need this encouragement in our afflictions.  And who can hope to escape these in a vale of tears?  Now, nothing is so desirable in our sufferings as to see not only the hand but the kindness of God in them.  For often, they look like the effects of His wrath and we tremble under them and cry, “Do not condemn me.  I could bear these trials if I thought they were only the strokes of a father’s rod, sent in love.”  And, they are sent in love.  They are only the strokes of a Father’s rod, laid hold of with reluctance and laid aside with pleasure.'(William Jay)

4 I do not sit with deceitful men,
nor do I consort with hypocrites;
5 I abhor the assembly of evildoers
and refuse to sit with the wicked.
6 I wash my hands in innocence,
and go about your altar, O LORD,
7 proclaiming aloud your praise
and telling of all your wonderful deeds.
8 I love the house where you live, O LORD,
the place where your glory dwells.

9 Do not take away my soul along with sinners,
my life with bloodthirsty men,
10 in whose hands are wicked schemes,
whose right hands are full of bribes.
11 But I lead a blameless life;
redeem me and be merciful to me.

12 My feet stand on level ground;
in the great assembly I will praise the LORD.
