Famous quotes containing the words additional and/or image:

“The world will never be long without some good reason to hate the unhappy; their real faults are immediately detected, and if those are not sufficient to sink them into infamy, an additional weight of calumny will be superadded.”
—Samuel Johnson (1709–1784)

“For the Lord thy God is a jealous God among you.”
—Bible: Hebrew Deuteronomy, 6:15.

The words are also found in Exodus 20:5, referring to the second commandment: “Thou shalt not make unto thee any graven image ... for I the Lord thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me.”
