This prayer of Baruch continues by asking God to look down from his heavenly holy dwelling. He should consider their situation. God should incline his ear and listen. He should open his eyes and see. The dead in Hades or Sheol have no spirit. They cannot give glory or justice to the Lord. On the other hand, those who are still living, but grieving, bent over, and feeble with poor eye sight can still declare the glory and righteousness of the Lord. Thus it is better to be alive and weak than dead.
Psalm 116 is a thanksgiving psalm without any titles. This psalm begins with the psalmist talking about how he loves Yahweh because Yahweh has heard his voice. Unlike the psalms that ask God to listen, this psalmist has already had his prayers answered. Yahweh heard his voice and supplications because he inclined his ear to him. The result is that he will always call upon Yahweh as long as he lives. He apparently was near his death in great distress and anguish almost near Sheol. Then he called out the name of Yahweh and he was saved. This is like a call to prayer for the others in the congregation.
Psalm 86 seems like a personal prayer of David. There is no other indication in the title. David wanted Yahweh to listen to him by giving him his ear. He wanted an answer since he was poor and needy. He wanted to preserve his life since he was devoted to Yahweh. He trusted in Yahweh as a servant. All day long he cried to Yahweh, his God. He wanted Yahweh to be gracious to him and gladden his soul. He knew that Yahweh was good and forgiving due to his steadfast love. David wanted Yahweh to hear him in the times of his trouble. He called and expected an answer.
The psalmist calls to God to answer him. He wanted God to turn his ear toward him. This is a common theme of God listening with his ear. He wanted God to hear his words. He wanted God to show his love. He wanted protection from his adversaries. He was seeking love and refuge in God.
