2 Samuel 13:3

13:3 Now Amnon had a friend named Jonadab, the son of David’s brother Shimeah. Jonadab was a very crafty man.

2 Samuel 15:31

15:31 Now David ¹  had been told, “Ahithophel has sided with the conspirators who are with Absalom. So David prayed, ²  “Make the advice of Ahithophel foolish, O Lord!”

2 Samuel 16:23

16:23 In those days Ahithophel’s advice was considered as valuable as a prophetic revelation. ³  Both David and Absalom highly regarded the advice of Ahithophel. ⁴ 

[15:31]  ¹ tc The translation follows 4QSam^a, part of the Greek tradition, the Syriac Peshitta, Targum, and Vulgate uldavid in reading “and to David,” rather than MT וְדָוִד (vÿdavid, “and David”). As Driver points out, the Hebrew verb הִגִּיד (higgid, “he related”) never uses the accusative for the person to whom something is told (S. R. Driver, Notes on the Hebrew Text and the Topography of the Books of Samuel, 316).

[15:31]  ² tn Heb “said.”

[16:23]  ³ tn Heb “And the advice of Ahithophel which he advised in those days was as when one inquires of the word of God.”

[16:23]  ⁴ tn Heb “So was all the advice of Ahithophel, also to David, also to Absalom.”
