David may have been referring in this psalm to an ancient custom observed by mourners at funerals. They would collect the tears they shed for departed loved ones in small flasks and place them in their tombs as memorials of their love. The New International Version renders this phrase as “list my tears on your scroll.”
But in a marginal note, it cites “put my tears in your wineskin” as a possible reading.
This was David’s way of saying that God knows all about us. He even keeps a record of the tears we shed in our moments of sorrow and sadness. Jesus expressed the same truth when He declared, “The very hairs of your head are all numbered” (Matthew 10:30).
PSALM 56:8- Thou [God] tellest my wanderings: put thou my tears into thy bottle: are they not in thy book?
