God Told Abraham that his decendents would have Shechem
Judges 9:26 ASV and Judges 9:28 ASV
Genesis 12:6-86 Abram passed through the land as far as the site of Shechem, to the oak of Moreh. Now the Canaanite was then in the land.7 The Lord appeared to Abram and said, “To your descendants I will give this land.” So he built an altar there to the Lord who had appeared to him.8 Then he proceeded from there to the mountain on the east of Bethel, and pitched his tent, with Bethel on the west and Ai on the east; and there he built an altar to the Lord and called upon the name of the Lord .
Jacob bought a piece of the land.
Genesis 33:19 He bought the piece of land where he had pitched his tent from the hand of the sons of Hamor, Shechem’s father, for one hundred pieces of money.
God told Jacob also that he would give him and his desendents the land that he told Abraham of.
Genesis 35:12
“The land which I gave to Abraham and Isaac,
I will give it to you,
And I will give the land to your descendants after you.”
13 Then God went up from him in the place where He had spoken with him.
14 Jacob set up a pillar in the place where He had spoken with him, a pillar of stone, and he poured out a drink offering on it; he also poured oil on it.
15 So Jacob named the place where God had spoken with him, Bethel.
Judges 6:15 He (Gideon or Jerubbaal) said to Him, "O Lord, how shall I deliver Israel? Behold, my family is the least in Manasseh, and I am the youngest in my father's house."
Judges 8:23
But Gideon said to them, "I will not rule over you, nor shall my son rule over you; (M)the LORD shall rule over you."
Judges 8:31
His (Gideon or Jerubbaal) concubine who was in Shechem also bore him a son, and he named him Abimelech.
Judges 8:33-35
33 Then it came about, as soon as Gideon was dead, that the sons of Israel again played the harlot with the Baals, and made Baal-berith their god.
34 Thus the sons of Israel (T)did not remember the LORD their God, who had delivered them from the hands of all their enemies on every side;
35 nor did they show kindness to the household of Jerubbaal (that is, Gideon) in accord with all the good that he had done to Israel.
Judges 9 1-2
1 And Abimelech the son of Jerubbaal went to Shechem to his mother's relatives, and spoke to them and to the whole clan of the household of his mother's father, saying,
2"Speak, now, in the hearing of all the leaders of Shechem, 'Which is better for you, that seventy men, all the sons of Jerubbaal, rule over you, or that one man rule over you?' Also, remember that I am your bone and your flesh."
Judges 10:19-20
19 if then you have dealt in truth and integrity with Jerubbaal and his house this day, rejoice in Abimelech, and let him also rejoice in you.
20 "But if not, let fire come out from Abimelech and consume the men of Shechem and Beth-millo; and let fire come out from the men of Shechem and from Beth-millo, and consume Abimelech."
Judges 9:52-53
52 So Abimelech came to the tower and fought against it, and approached the entrance of the tower to burn it with fire.
53 But a certain woman threw an upper millstone on Abimelech's head, crushing his skull.
Judges 9:55-57
55 When the men of Israel saw that Abimelech was dead, each departed to his home.
56 Thus God repaid the wickedness of Abimelech, which he had done to his father in killing his seventy brothers.
57 Also God returned all the wickedness of the men of Shechem on their heads, and the curse of Jotham the son of Jerubbaal came upon them.
