Discovery Box2 Samuel 21:17 
Context21:17 But Abishai the son of Zeruiah came to David’s aid, striking the Philistine down and killing him. Then David’s men took an oath saying, “You will not go out to battle with us again! You must not extinguish the lamp of Israel!”
2 Samuel 14:7
Context14:7 Now the entire family has risen up against your servant, saying, ‘Turn over the one who struck down his brother, so that we can execute him and avenge the death 1 of his brother whom he killed. In so doing we will also destroy the heir.’ They want to extinguish my remaining coal, 2 leaving no one on the face of the earth to carry on the name of my husband.”
1 tn Heb “in exchange for the life.” The Hebrew preposition בְּ (bÿ, “in”) here is the so-called bet pretii, or bet (בְּ) of price, defining the value attached to someone or something.
2 sn My remaining coal is here metaphorical language, describing the one remaining son as her only source of lingering hope for continuing the family line.
