The Great Mystery of God Part I - God's Name in the Old Testament

In the Old Testament, God's name was JEHOVAH, the God of Abraham, Isaac and Jacob (Ex. 6:3, Ps. 83:18, Isa. 12:2, Isa. 26:4). These three persons were so obedient with God's commandments. When Jacob was tested and won the fight with an angel, God blessed him and changed his name to Israel (Gen. 32:28). Jacob's offsprings (the Israelites) were fruitful and multiplied greatly and became exceedingly numerous (Ex. 1:7). Israelites were the chosen people of God. He took them out of Egypt and freed them from the bondage of slavery for almost 430 years (Ex. 12:40-41). God promised them a land (Genesis 15:18-19), which is called now Israel (after Jacob's name). God's love for this nation was so great (Deut. 7:1-26), but when their forfathers died, the new generation despised God's covenant and did evil in the eyes of the Lord (Judges 2:10-23). They provoked Him to anger, and they even profaned His Holy Name (Eze. 36:16-23), so He sworn His Great Name (Jer. 44:26) and promised a "new name" that shall not be cut off (Isa. 56:5, Isa. 63:12) and a new covenant (Isa 55:1-3, Jer. 31:31-32).
