Romans 3:4
Clementine Vulgate · Berean Standard Bible
Est autem Deus verax : omnis autem homo mendax, sicut scriptum est : Ut justificeris in sermonibus tuis : et vincas cum judicaris.
Certainly not! Let God be true and every man a liar. As it is written: “So that You may be proved right when You speak and victorious when You judge (note: Or when You are judged; Psalm 51:4 (see also LXX)).”
