“Now therefore so shalt thou say vnto my seruant Dauid; Thus sayth the Lord of hostes, I tooke thee from the sheepe-cote, from following the sheepe, to be ruler ouer my people, ouer Israel.”
1611 King James Version (KJV)
7:8 My servant - Lest David should be too much discouraged, or judge himself neglected of God, as one thought unworthy of so great an honour, God here gives him the honourable title of his servant, thereby signifying that he accepted of his service, and good intentions.
