Malachi 1:6
5 Your eyes will see it, and then you will say, ‘May the Lord be magnified even beyond the border of Israel!’” 6 “A son naturally honors his father and a slave respects his master. If I am your father, where is my honor? If I am your master, where is my respect? The Lord of Heaven’s Armies asks you this, you priests who make light of my name! But you reply, ‘How have we made light of your name?’ 7 You are offering improper sacrifices on my altar, yet you ask, ‘How have we offended you?’ By treating the table of the Lord as if it is of no importance.
Luke 6:46
45 The good person out of the good treasury of his heart produces good, and the evil person out of his evil treasury produces evil, for his mouth speaks from what fills his heart. 46 “Why do you call me ‘Lord, Lord,’ and don’t do what I tell you? 47 “Everyone who comes to me and listens to my words and puts them into practice—I will show you what he is like: 48 He is like a man building a house, who dug down deep and laid the foundation on bedrock. When a flood came, the river burst against that house but could not shake it because it had been well built.
Notes and References
"... There are some other simple allusions to Malachi in Luke. One of them is the Greek word (behold). Though the Greek word (behold) often occurs in Luke, it is especially used to emphasize John's birth (1:20) and Jesus' birth (1:31, 35). It is reminiscent of the Hebrew word (behold) which is twice used in Malachi 3:1, linked with two different eschatological figures' arrival. In light of the study of the relationship between Malachi and Luke, Luke must have had in his mind Malachi's eschatological figures - Elijah and Ha Adon - when he recorded John's and Jesus' birth. The citation in Luke 6:46 may be an allusion to Malachi 1:6 perhaps based upon the form and spirit of the rhetorical question posed by Jesus. Doble surmises that the Coming One may be suggested in Luke 7:16, and he seems to link the Coming One concept to Malachi‘s eschatological Elijah ..."
