New American Standard Bible (NASB)
2 Samuel 24
24 However, the king said to Araunah, "No, but I will surely buy it from you for a price, for I will not offer burnt offerings to the Lord my God which cost me nothing." So David bought the threshing floor and the oxen for fifty shekels of silver.
25 David built there an altar to the Lord and offered burnt offerings and peace offerings. Thus the Lord was moved by prayer for the land, and the plague was held back from Israel.
1 Kings 1
1 Now King David was old, advanced in age; and they covered him with clothes, but he could not keep warm.
2 So his servants said to him, "Let them seek a young virgin for my lord the king, and let her attend the king and become his nurse; and let her lie in your bosom, that my lord the king may keep warm."
3 So they searched for a beautiful girl throughout all the territory of Israel, and found Abishag the Shunammite, and brought her to the king.
4 The girl was very beautiful; and she became the king’s nurse and served him, but the king did not cohabit with her.
5 Now Adonijah the son of Haggith exalted himself, saying, "I will be king." So he prepared for himself chariots and horsemen with fifty men to run before him.
6 His father had never crossed him at any time by asking, "Why have you done so?" And he was also a very handsome man, and he was born after Absalom.
7 He had conferred with Joab the son of Zeruiah and with Abiathar the priest; and following Adonijah they helped him.
8 But Zadok the priest, Benaiah the son of Jehoiada, Nathan the prophet, Shimei, Rei, and the mighty men who belonged to David, were not with Adonijah.
9 Adonijah sacrificed sheep and oxen and fatlings by the stone of Zoheleth, which is beside En-rogel; and he invited all his brothers, the king’s sons, and all the men of Judah, the king’s servants.
