New Defender's Study Bible Notes
16:13 Spirit of the LORD. See note on I Samuel 16:14. The Spirit of the Lord also had come on Othniel (Judges 3:10, Jephthah (Judges 11:29), and Samson (Judges 13:25), but these were all merely temporary enablings for specific accomplishments.
16:13 came upon David. This is the first time David is mentioned by name, but his name (meaning “beloved”) is mentioned more in the Bible than that of Moses or Abraham or any other Old Testament personage. His biography occupies sixty-two chapters, more than that of anyone else except Jesus Christ.
