In captivity in Babylon, with Zion just a memory, the people of God longed for their proper home; the frustration of alienation drove them to tears.
“By the rivers of Babylon we sat and wept when we remembered Zion. There on the poplars we hung our harps, for there our captors asked us for songs, our tormentors demanded songs of joy; they said. “Sing us one of the songs of Zion!” Psalm 137:1-3
David, the musician/soldier, king of Judah, also came to feel alienated from God, by his enemies and by his sins; more than once.
But David discovered that God had not left him in his anxiety; he said, ‘…the LORD has heard the voice of my weeping…’ KJV
Other translations are, ‘the LORD has heard my weeping’ or ‘has heard the sound of my weeping’ but ‘the voice of my weeping’ speaks to me; so to speak.
When our experience of Babylon, or the sins of others, or our own sins drive us to tears of frustration or tears of repentance David says that the LORD hears us.
God has heard ‘my cry for mercy’; he ‘accepts my prayer’ and, when words let me down, the LORD hears, and accepts, ‘the voice of my weeping’.
When first century Christians in Rome, persecuted for faith, began to long for their proper home in the company of Christ, Paul reassured them of this too.
‘In the same way, the Spirit helps us in our weakness. We do not know what we ought to pray for, but the Spirit himself intercedes for us with groans that words cannot express. And he who searches our hearts knows the mind of the Spirit, because the Spirit intercedes for the saints in accordance with God’s will.’ Romans 8:26, 27
