Morning Direction From Scripture 6-8-19

I heard an unknown voice say:

6 “I removed the burden from their shoulders;
    their hands were set free from the basket.
7 In your distress you called and I rescued you,
    I answered you out of a thundercloud;
    I tested you at the waters of Meribah.[c]
8 Hear me, my people, and I will warn you—
    if you would only listen to me, Israel!
9 You shall have no foreign god among you;
    you shall not worship any god other than me.
10 I am the Lord your God,
    who brought you up out of Egypt.
Open wide your mouth and I will fill it.

Psalm 81:5-10

Why do you think the voice is unknown? What does it say about the author of the Psalm?

Mid Afternoon Meditation 6-7-19

Sing for joy to God our strength;
    shout aloud to the God of Jacob!
2 Begin the music, strike the timbrel,
    play the melodious harp and lyre.

3 Sound the ram’s horn at the New Moon,
    and when the moon is full, on the day of our festival;
4 this is a decree for Israel,
    an ordinance of the God of Jacob.
5 When God went out against Egypt,
    he established it as a statute for Joseph. Psalm 81:1-5

How is worship a form of spiritual warfare? (see vs. 5)

    he established it as a statute for Joseph. Psalm 81:1-5

How do you feel about praising God being a command?
