1st Samuel 16:13 Then Samuel took the horn of oil, and anointed him in the midst of his brethren: and the Spirit of the Lord came upon David from that day forward. So Samuel rose up, and went to Ramah.
[Patriarchs & Prophets pp 641] The lonely shepherd was startled by the unexpected call of the messenger, who announced that the prophet had come to Bethlehem and had sent for him. With surprise he questioned why the prophet and judge of Israel should desire to see him; but without delay he obeyed the call. “Now he was ruddy, and withal of a beautiful countenance, and goodly to look to.” As Samuel beheld with pleasure the handsome, manly, modest shepherd boy, the voice of the Lord spoke to the prophet, saying, “Arise, anoint him: for this is he.”
David had proved himself brave and faithful in the humble office of a shepherd, and now God had chosen him to be captain of His people. “Then Samuel took the horn of oil, and anointed him in the midst of [from among] his brethren: and the Spirit of the Lord came upon David from that day forward.” The prophet had accomplished his appointed work, and with a relieved heart he returned to Ramah. Samuel had not made known his errand, even to the family of Jesse, and the ceremony of anointing David had been performed in secret.
It was an intimation to the youth of the high destiny awaiting him, that amid all the varied experiences and perils of his coming years, this knowledge might inspire him to be true to the purpose of God to be accomplished by his life. The great honor conferred upon David did not serve to elate him. Notwithstanding the high position which he was to occupy, he quietly continued his employment, content to await the development of the Lord's plans in His own time and way.
Micah 6:8 He hath shewed thee, O man, what is good; and what doth the Lord require of thee, but to do justly, and to love mercy, and to walk humbly with thy God?
May The Lord add His blessing to the study of His word. God bless!
