What song was sung in what environment?

[Classic old song] "What song to sing under what circumstances" is a Christian hymn, which can be used as singing.

The lyrics of "What song is sung in what environment" are as follows:

You should be happy in whatever environment you sing. You should rejoice that the devil is retreating and sing praises to God happily. Sing a song of praise to the Lord happily.

With the environment, don't back down. Trying to be true and false makes you and me. Look at yourself and don't look at other people's mistakes. How can you offend the Lord and enter the kingdom of heaven by gossiping?
