Psalm 139:1-15 and Isaiah 49:1-6

Psalm 139:1-15
1 Unto the end. A Psalm of David. O Lord, you have examined me, and you have known me.
2 You have known my sitting down and my rising up again.
3 You have understood my thoughts from afar. My path and my fate, you have investigated.
4 And you have foreseen all my ways. For there is no word in my tongue.
5 Behold, O Lord, you have known all things: the newest and the very old. You have formed me, and you have placed your hand over me.
6 Your knowledge has become a wonder to me. It has been reinforced, and I am not able to prevail against it.
7 Where will I go from your Spirit? And where will I flee from your face?
8 If I ascend into heaven, you are there. If I descend into Hell, you are near.
9 If I assume my feathers in early morning, and dwell in the utmost parts of the sea,
10 even there, your hand will lead me forth, and your right hand will hold me.
11 And I said: Perhaps darkness will overwhelm me, and the night will be my illumination, to my delight.
12 But darkness will not be impenetrable to you, and night will illuminate like the day: for just as its darkness is, so also is its light.
13 For you have possessed my temperament. You have supported me from the womb of my mother.
14 I will confess to you, for you have been magnified terribly. Your works are miraculous, as my soul knows exceedingly well.
15 My bone, which you have made in secret, has not been hidden from you, and my substance is in accord with the lower parts of the earth.
Isaiah 49:1-6
1 Pay attention, you islands, and listen closely, you far away peoples. The Lord has called me from the womb; from the womb of my mother, he has been mindful of my name.
2 And he has appointed my mouth as a sharp sword. In the shadow of his hand, he has protected me. And he has appointed me as an elect arrow. In his quiver, he has hidden me.
3 And he has said to me: "You are my servant, Israel. For in you, I will glory."
4 And I said: "I have labored toward emptiness. I have consumed my strength without purpose and in vain. Therefore, my judgment is with the Lord, and my work is with my God."
5 And now, says the Lord, who formed me from the womb as his servant, so that I may bring back Jacob to him, for Israel will not be gathered together, but I have been glorified in the eyes of the Lord and my God has become my strength,
6 and so he has said: "It is a small thing that you should be my servant so as to raise up the tribes of Jacob, and so as to convert the dregs of Israel. Behold, I have offered you as a light for the Gentiles, so that you may be my salvation, even to the furthest regions of the earth."
