God's Love for Israel is shown by his deeds towards Esau (Edom)
1 The burden of the word of the Lord to Israel by Malachi.
2 “I have loved you,” says the Lord. “Yet you say, ‘In what way have You loved us?’ Was not Esau Jacob’s brother?” Says the Lord. “Yet Jacob I have loved;
3 But Esau I have hated, And laid waste his mountains and his heritage For the jackals of the wilderness.”
4 Even though Edom has said, “We have been impoverished, But we will return and build the desolate places,” Thus says the Lord of hosts: “They may build, but I will throw down; They shall be called the Territory of Wickedness, And the people against whom the Lord will have indignation forever.
5 Your eyes shall see, And you shall say, ‘The Lord is magnified beyond the border of Israel.’
Malachi 1:1-5
God remain consistent about Edom
1 Who is this who comes from Edom, With dyed garments from Bozrah, This One who is glorious in His apparel, Traveling in the greatness of His strength?— “I who speak in righteousness, mighty to save.”
2 Why is Your apparel red, And Your garments like one who treads in the winepress?
3 “I have trodden the winepress alone, And from the peoples no one was with Me. For I have trodden them in My anger, And trampled them in My fury; Their blood is sprinkled upon My garments, And I have stained all My robes.
4 For the day of vengeance is in My heart, And the year of My redeemed has come.
5 I looked, but there was no one to help, And I wondered That there was no one to uphold; Therefore My own arm brought salvation for Me; And My own fury, it sustained Me.
6 I have trodden down the peoples in My anger, Made them drunk in My fury, And brought down their strength to the earth.”
Isaiah 63:1-6
Also in the New Testament
11 (for the children not yet being born, nor having done any good or evil, that the purpose of God according to election might stand, not of works but of Him who calls),
12 it was said to her, “The older shall serve the younger.”
13 As it is written, “Jacob I have loved, but Esau I have hated.”
14 What shall we say then? Is there unrighteousness with God? Certainly not!
15 For He says to Moses, “I will have mercy on whomever I will have mercy, and I will have compassion on whomever I will have compassion.”
16 So then it is not of him who wills, nor of him who runs, but of God who shows mercy.
17 For the Scripture says to Pharaoh, “For this very purpose I have raised you up, that I may show My power in you, and that My name may be declared in all the earth.”
18 Therefore He has mercy on whom He wills, and whom He wills He hardens.
19 You will say to me then, “Why does He still find fault? For who has resisted His will?”
20 But indeed, O man, who are you to reply against God? Will the thing formed say to him who formed it, “Why have you made me like this?”
Romans 9:11-20
