Turn on your auditory imagination here.
from the OT [Cymbals, brass, and strings - no sound techs]:
. . . All the people dedicated to God who were musicians— and their sons and relatives—stood on the east side of the church altar, dressed in fine linen and playing cymbals, harps and lyres.
They were accompanied by 120 more people sounding trumpets. The trumpeters and singers joined in unison, as with one voice, to give praise and thanks to the LORD.
Accompanied by trumpets, cymbals and other instruments, they raised their voices in praise to the LORD and sang:
"He is good;
his love endures forever."
Then the temple of the LORD was filled with a cloud, and the pastors could not perform their service because of the cloud, for the glory of the LORD filled the temple of God.
Were the children there?
From the NT:
Be joyful always; pray continually; give thanks in all circumstances, for this is God's will for you in Christ Jesus . . .
Do not put out the Spirit's fire . . . May God himself, the God of peace, sanctify you through and through. May your whole spirit, soul and body be kept blameless at the coming of our Lord Jesus Christ. The one who calls you is faithful and he will do it.
When someone was reading Paul's letters to a house church, were the children there?
