Oh, That My People Would Listen to Me

To the choirmaster: according to gThe Gittith.
Probably a musical or liturgical term
Of iAsaph.

1 jSing aloud to God our strength;
kshout for joy to the God of Jacob!
2Raise a song; sound lthe tambourine,
mthe sweet lyre with nthe harp.
3Blow the trumpet at othe new moon,
at the full moon, on our feast day.
4 For it is a statute for Israel,
a rule
Or just decree
of the God of Jacob.

Isaiah 1:13-14

13Bring no more vain offerings;
incense is an abomination to me.
qNew moon and Sabbath and the rcalling of convocations
I cannot endure siniquity and tsolemn assembly.
14Your unew moons and your appointed feasts
my soul hates;
they have become a burden to me;
I am weary of bearing them.
