Lord, master

Boyd’s Bible Dictionary:

“Lord” From Concise Bible Dictionary:

1. adon, κύριος. These words are commonly translated “lord.” They are used as a term of respect as between man and man, as seen in the children of Heth to Abraham (Gen. 23:66Hear us, my lord: thou art a mighty prince among us: in the choice of our sepulchres bury thy dead; none of us shall withhold from thee his sepulchre, but that thou mayest bury thy dead. (Genesis 23:6)); between servants and masters, and once by a wife to her husband (Gen. 18:1212Therefore Sarah laughed within herself, saying, After I am waxed old shall I have pleasure, my lord being old also? (Genesis 18:12); Luke 16:3,53Then the steward said within himself, What shall I do? for my lord taketh away from me the stewardship: I cannot dig; to beg I am ashamed. (Luke 16:3)
5So he called every one of his lord's debtors unto him, and said unto the first, How much owest thou unto my lord? (Luke 16:5)
; 1 Pet. 3:66Even as Sara obeyed Abraham, calling him lord: whose daughters ye are, as long as ye do well, and are not afraid with any amazement. (1 Peter 3:6)). The title “Lord” is applied to God (Psalm 90:11<<A Prayer of Moses the man of God.>> Lord, thou hast been our dwelling place in all generations. (Psalm 90:1), Adonai), and in the New Testament to the Lord Jesus, not only as a term of respect, but as owning His constituted lordship (Acts 2:3636Therefore let all the house of Israel know assuredly, that God hath made that same Jesus, whom ye have crucified, both Lord and Christ. (Acts 2:36); Phil. 2:1111And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father. (Philippians 2:11)). He is emphatically the Lord as eclipsing every other for the Christian, who delights to appropriate Him as “My Lord” (Luke 1:4343And whence is this to me, that the mother of my Lord should come to me? (Luke 1:43); John 20:1313And they say unto her, Woman, why weepest thou? She saith unto them, Because they have taken away my Lord, and I know not where they have laid him. (John 20:13); Phi. 3:8). To believers collectively He is “Our Lord Jesus Christ.”

“Master” From Concise Bible Dictionary:

In the Old Testament there are five words so translated, but only one that occurs frequently, adon, which is often rendered “Lord,” and signifies “master” either as owner or ruler. In the New Testament there is 1. κύριος, often translated “Lord”; this is rendered “master” in reference to God in Ephesians 6:99And, ye masters, do the same things unto them, forbearing threatening: knowing that your Master also is in heaven; neither is there respect of persons with him. (Ephesians 6:9) and Colossians 4:11Masters, give unto your servants that which is just and equal; knowing that ye also have a Master in heaven. (Colossians 4:1); and is often used as between master and servants.
