Proverbs 18:13 warns against answering before listening—parallel to the need for cross-examination before judging.

In 2 Samuel 16:1-3, David hears Ziba's side first and believes him—a classic case of the first speaker seeming right.

In 2 Samuel 19:24-27, Mephibosheth cross-examines Ziba's accusation, fulfilling the proverb's second half.

In Acts 24:5, Tertullus presents a one-sided accusation against Paul, exemplifying how the first speaker seems right.

Acts 24:13 shows Paul refuting false accusations — the one-sided case seemed right until his defense, illustrating the proverb's wisdom.

In Genesis 39:19, Potiphar believes his wife's accusation without hearing Joseph — a classic case of judging prematurely.

2 Samuel 16:4 has David accepting Ziba's lie about Mephibosheth without hearing the other side — exactly the danger described.

Acts 25:16 states Roman law requires accuser and accused to face each other — a direct application of the proverb's principle.
