Psalm 42:3

Ps 42.3
My tears have been my food day and night,
while men say to me all day long, "Where is your God?"

These were his companions saying this, not his enemies. He was traveling with a band of soldiers. They would have been the ones who spoke with him.

Be encouraged when the people closest to you doubt your faith. It is nothing new (Ecc 1.9), and you're in good company.

Blessings
