In order to notify the slaves on other farms when there was going to be a meeting they would sing this song, and the slaves would understand what it meant. White people would think they were only singing for amusement:

“Get you ready, there’s a meeting here tonight.” Matt. 7: 16.

1
Get you ready, there’s a meeting here tonight,
Come along there’s a meeting here tonight,
I know you by your daily walk,
There’s a meeting here tonight.

2
Oh, hallelujah, to the lamb,
There’s a meeting here tonight,
For the Lord is on the given hand,
There’s a meeting here tonight.

3
If ever I reach the mountain top,
I’ll praise my Lord and never stop,
Get you ready, there’s a meeting here tonight.

4
Go down to the river when you’re dry
And there you’ll get your full supply,
Get ready, there’s a meeting here tonight.

5
You may hinder me here,
But you cannot there,
God sits in heaven
And he answers prayer.
There’s a meeting here tonight.

They would carry with them iron lamps, with a greasy rag for a wick, and they would attach a sharp spike to the lamp so as to stick it in a tree. In this way they would light up the swamp, while they held their meeting.
