⁴ Behold, you fast for strife and contention, and to strike with the fist of wickedness: you don’t fast this day so as to make your voice to be heard on high.

⁴ Behold, you fast only to quarrel and to fight and to hit with wicked fist. Fasting like yours this day will not make your voice to be heard on high.

⁴ You fast, but at the same time you bicker and fight. You fast, but you swing a mean fist. The kind of fasting you do won't get your prayers off the ground.
