"God, redeem Israel out of all his troubles" (25:22). Why does a prayer of "me" and "my" end with Israel?

The psalm doesn't say. What it shows is this. The psalm's other prayers are the psalmist's for himself: "Show me your ways, LORD" (25:4), "Turn to me, and have mercy on me" (25:16). The last verse is the only one in the psalm that names Israel. It comes after the verse that begins with tav, the alphabet's last letter (25:21), and it begins with pe (the first section of these notes sets out the letters). Its troubles is the Hebrew word of "The troubles of my heart are enlarged" (25:17): the psalmist asks about his own troubles in 25:17, and Israel's in 25:22. Psalm 130 ends with almost the same Hebrew words: "He will redeem Israel from all their sins" (Psalm 130:8). The psalm gives no reason for its last verse, and these notes don't give one.
