John Gill Commentary Ezekiel 23:32

"Thus saith the Lord Jehovah: Thou shalt drink of thy sister`s cup, which is deep and large; thou shalt be laughed to scorn and had in derision; it containeth much." — Ezekiel 23:32 (ASV)

Thus says the Lord God, you shall drink of your sister's cup
deep and large
That is, partake of the same punishment, which was very great, signified by a deep and large cup, which holds much:

you shall be laughed to scorn, and had in derision ;
by the nations round about, who, instead of pitying them under their troubles, will rejoice at them; just as drunken men are laughed at, when intoxicated and reeling about:

it contains much ;
the cup of wrath and vengeance; as much as will last severity years drinking.

The Targum connects this with the preceding clause, "and you shall be for derision and for laughter, because of the greatness of the tribulation that shall come upon you."
