Psalm 63 is thought to have been written when David was hiding from his enemies in the Desert of Judah. What gets David through this time of danger in the desert is remembering the strength of God. He recalls God's power and glory, his love and help. In the midst of lack he experiences God's presence as the richest of foods and praises the Lord with dry, cracked lips. With lifted hands he sings to God though his tongue is parched and swollen.
What a testimony this prayer is. Even though he is on the run, David praises God for his deliverance and victory over his enemies. He looks toward the future when all who swear by God's name will praise him. In the worst of situations, with death all around him, with no one to help him, he trusts in God, believes in God, praises God. David hangs on and triumphs.
O God, you are my God, earnestly I seek you;
my soul thirsts for you, my body longs for you,
in a dry and weary land where there is no water.
