Here is, 1. God's care of David to protect and defend him, which he
comforted himself with when his enemies were very malicious against
him: Thou art my hiding-place and my shield. David, when Saul pursued
him, often betook himself to close places for shelter; in war he
guarded himself with his shield. Now God was both these to him, a
hiding-place to preserve him from danger and a shield to preserve him
in danger, his life from death and his soul from sin. Good people are
safe under God's protection. He is their strength and their shield,
their help and their shield, their sun and their shield, their shield
and their great reward, and here their hiding-place and their shield.
They may by faith retire to him, and repose in him as their
hiding-place, where they are kept in secret. They may by faith oppose
his power to all the might and malice of their enemies, as their shield
to quench every fiery dart. 2. David's confidence in God. He is safe,
and therefore he is easy, under the divine protection: "I hope in thy
word, which has acquainted me with thee and assured me of thy kindness
to me." Those who depend on God's promise shall have the benefit of his
power and be taken under his special protection.
