1 Samuel 16:13

in the midst of his brethren This can only mean "in the presence of his brethren." As in the subsequent history they do not seem to have any idea of their brother's high destiny, the true significance of the act appears to have been concealed from them. Whether it was made clear even to Jesse and David himself may be doubted. They may have supposed that Samuel had selected David for a pupil in his prophetic school. See 1 Samuel 19:18 ff.

the spirit of the Lord came upon David As upon Saul at the first (1 Samuel 10:6). For "came upon" see note on 1 Samuel 11:6. The special supernatural preparation for his office began from that hour.

David The name means "beloved" or "darling," and was probably given to him as the youngest of the family.
