Isaiah 1:19–20 (NKJV)
19 If you are willing and obedient, You shall eat the good of the land; 20 But if you refuse and rebel, You shall be devoured by the sword”; For the mouth of the Lord has spoken.
The pun in the warning is made clear in the Hebrew but obscured in this translation. The Hebrew word for "eat" (v19) and "be devoured" (v20) is the same - 'akal.
The "mouth" of Yahweh says this: either eat or be eaten. Obey and find the fruit of the land. Rebel and find yourself on the cutting board.
