To whom shall I speak, and give warning, that they may hear? behold, their ear is uncircumcised, and they cannot hearken: behold, the word of the LORD is unto them a reproach; they have no delight in it.
Ear is uncircumcised - closed against the precepts of God by the foreskin of carnality (Leviticus 26:41, "uncircumcised hearts;" Ezekiel 44:7; Acts 7:51, "uncircumcised in heart and ears").
Word of the Lord is unto them a reproach - (Jeremiah 20:8, "The word of the Lord was made a reproach unto me, and a derision daily").
