2 Samuel 4 — David ain’t your ordinary king. He doesn’t find pleasure in the things that other kings do. He has a much better sense of justice. If only he could have maintained that for his entire reign.
2 Samuel 5 — There are some significant numbers in vv. 4-5. David began his reign at 30 (v. 4), the same age that Joseph was when he began to serve Pharaoh (Gen. 41:46); the same age John the Baptist probably was (if he started his ministry in the 15th year of Tiberius’ reign [Luke 3:1-2]] than that would have been AD 29, he was 6 months older than Jesus, who probably began his ministry in AD 30, so that works out to John probably being 30); the same age as Jesus when he began his public ministry (Luke 3:23). And 30, of course, is the age that Levites would start serving in the temple (Num. 4). Bullinger says that 30 is the number of dedication; I’d add institution. David was a priestly king as was Jesus. 30 represents dedication. David reigned 40 years (v. 4) and 40 represents trials and testing (e.g., Israel’s 40 years in the wilderness; Jesus’ 40 days of fasting; etc.). We’ll read of the various trials and tests that David went through as the narrative progresses. He reigned 7 years in Hebron (v. 5), which were his best years; the years before he succumbed to temptation and fell. 7 represents perfection.
2 Samuel 6 — The ark of the covenant carried God’s anointing/glory. We see two different ramifications of this in this chapter. On the one hand, those who improperly handle God’s anointing/glory die, as in the case of Uzzah (vv. 6-7); but on the other hand, those who reside in the presence of God’s glory/anointing can’t help but be blessed, as in the case of Obed-edom and his household (vv. 11-12). Michal was more like her father than Jonathan was (v. 16) but David seems to have much more respect for Saul than for Michal since he couldn’t care less about how she felt about his dancing before the LORD (vv. 21-22), and this makes sense since Saul was God’s anointed and Michal was just a wife purchased for a couple hundred Philistine foreskins.
2 Samuel 7 — I never noticed that God described David as “following the sheep” (v. 8) before. It’s like a little light clicked when I read that. Of course it makes sense that God would choose David to lead; he had spent his youth following! How did Jesus put it, “If anyone would be first, he must be last of all and servant of all” (Mark 9:35). I can’t help but think of Ephesians 4:4-6 when I read vv. 22-24. Paul seems to be elaborating on this idea of one Lord who has one people whom he loves and delivers and sets apart for his purposes.
