Isaiah 1:13-15

13 Bring no more vain offerings;
incense is an abomination to me.
^hNew moon and Sabbath and the ⁱcalling of convocations—
I cannot endure ^jiniquity and ^ksolemn assembly.
14 Your ^lnew moons and your appointed feasts
my soul hates;
they have become a burden to me;
I am weary of bearing them.
15 When you ^mspread out your hands,
I will hide my eyes from you;
ⁿeven though you make many prayers,
I will not listen;
^oyour hands are full of blood.
