One of the themes of Psalm 84 seems to be "LORD of hosts." In this Psalm, "LORD of hosts" is used to refer to God at least four times. I was somewhat surprised as I studied how this Psalm develops this theme. It would seem that a Psalm about the LORD of hosts would be full of action and excitement and the battles of the Lord. But it is not. It is full of rest. The Lord fights the battles, but the LORD of hosts is our resting place. Below is an acrostic based on this Psalm.
LORD OF HOSTS
Resting place and restoration place
O God of Jacob
Hearer of my prayers
Our source of all good things
Sun to light our way
Strength, grace, and glory for His people
