God told Moses that He had heard the groaning of Israel and understood. Therefore God came down to deliver them. The Psalmist knew what God had done before and expected Him to do the same.
Psalm 102: 19-20
For He looked down from the height of His sanctuary; from heaven the Lord viewed the earth,
To hear the groaning of the prisoner, to release those appointed to death.
And God did. Yeshua applied these words (first given through the prophet Isaiah) to Himself:
“The Spirit of the Lord is upon Me, because He has anointed Me to preach the gospel to the poor; He has sent Me to heal the brokenhearted, to proclaim liberty to the captives and recovery of sight to the blind, to set at liberty those who are oppressed;
To proclaim the acceptable year of the Lord.”
PRAY FOR THE SALVATION AND REDEMPTION OF ISRAEL.
