5 You strum away on your harps like David

and improvise on musical instruments.

5 who sing idle songs to the sound of the harp

and like David invent for themselves instruments of music,

5 That chant to the sound of the viol, And invent to themselves instruments of musick, like David;

5 You sing trivial songs to the sound of the harp

and fancy yourselves to be great musicians like David.

5 Who sing idly to the sound of stringed instruments,

And invent for yourselves musical instruments like David;

5 You make up songs on your harps,

and, like David, you compose songs on musical instruments.

5 that sing idle songs to the sound of the viol; that invent for themselves instruments of music, like David;

5 that chant to the sound of the lute, and invent them instruments of music, like David;

5 How horrible it will be for those who make up songs as they strum a harp. 

Like David, they write all kinds of songs for themselves. 

5 They improvise songs to the sound of the harp

and invent their own musical instruments like David.

5 who sing idle songs to the sound of the harp,

and like David improvise on instruments of music;

5 Alas for those who sing to the tune of the harp; like David they improvise on instruments of music.

5 You pluck away on your harps as David did.

You play new songs on musical instruments.
