Psalm 16 is another positive sort of psalm. After asking the Lord for help, the speaker does not dwell on his own problems, but rather moves on to discuss the nature of God's mercy and justice.
In verses 2-3, the speaker begins addressing his own soul, sort of talking with himself about how he trusts God. He also supports God's saints, the other people who pursue excellence and serve the Lord. The speaker doesn't just like these people, he is delighted by them, which is more than a lot of us can say about the way we view our brothers and sisters in Christ.
Verse 4 briefly mentions the ungodly, who make offerings of blood to false gods, which disgusts the speaker. But the speaker moves right back to talking about his relationship with God in verses 5-6, which rejoice in the lot in life which God has assigned to him. He is happy with where is and with what has been given to him.
Verses 7-8 talk about being unshakable in your faith--the speaker keeps God in his thoughts constantly, so his actions can't stray too far from the right path.
Verses 9-11 are more praise and thankfulness, saying that God will not abandon the speaker, so he can rest. Verse 10 is actually considered a Messianic prophesy, about Jesus, because "neither wilt thou suffer thine Holy One to see corruption" is taken to mean that God would not allow Jesus to remain dead after the crucifixion.
The takeaway value of this psalm? Be content with the inheritance God has given you, and take joy in walking with God.
1Preserve me, O God: for in thee do I put my trust.
2 O my soul, thou hast said unto the Lord, Thou art my Lord: my goodness extendeth not to thee;
3 But to the saints that are in the earth, and to the excellent, in whom is all my delight.
4 Their sorrows shall be multiplied that hasten after another god: their drink offerings of blood will I not offer, nor take up their names into my lips.
5 The Lord is the portion of mine inheritance and of my cup: thou maintainest my lot.
6 The lines are fallen unto me in pleasant places; yea, I have a goodly heritage.
7 I will bless the Lord, who hath given me counsel: my reins also instruct me in the night seasons.
8 I have set the Lord always before me: because he is at my right hand, I shall not be moved.
9 Therefore my heart is glad, and my glory rejoiceth: my flesh also shall rest in hope.
10 For thou wilt not leave my soul in hell; neither wilt thou suffer thine Holy One to see corruption.
11 Thou wilt shew me the path of life: in thy presence is fulness of joy; at thy right hand there are pleasures for evermore.
