The blessings that God promised to Israel don't apply to Christians. God promised them that if they were obedient that they would never have the diseases that the Egyptians had. Nor would any female, human or animal, be without young.
Almost nobody refers to God as Jehovah. Except cults like the Jehovah's Witnesses.
We can't be saved and see heaven unless we repent of our sins, accept what Jesus did on the cross to pay for those sins, accept Jesus as Lord, and do what the Bible commands.
The cults completely ignore the godhood and purpose of Jesus. Those two things can be demonstrated in just a few verses although there are hundreds that would back them up.
(John 3:16-18 NIV) "For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. {17} For God did not send his Son into the world to condemn the world, but to save the world through him. {18} Whoever believes in him is not condemned, but whoever does not believe stands condemned already because he has not believed in the name of God's one and only Son.
(John 17:4-5 NIV) I have brought you glory on earth by completing the work you gave me to do. {5} And now, Father, glorify me in your presence with the glory I had with you before the world began.
(Hebrews 1:1-3 NIV) In the past God spoke to our forefathers through the prophets at many times and in various ways, {2} but in these last days he has spoken to us by his Son, whom he appointed heir of all things, and through whom he made the universe. {3} The Son is the radiance of God's glory and the exact representation of his being, sustaining all things by his powerful word. After he had provided purification for sins, he sat down at the right hand of the Majesty in heaven.
(Isaiah 9:6-7 NIV) For to us a child is born, to us a son is given, and the government will be on his shoulders. And he will be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace. {7} Of the increase of his government and peace there will be no end. He will reign on David's throne and over his kingdom, establishing and upholding it with justice and righteousness from that time on and forever. The zeal of the LORD Almighty will accomplish this.
(Psalms 72:1-8 NIV) Of Solomon. Endow the king with your justice, O God, the royal son with your righteousness. {2} He will judge your people in righteousness, your afflicted ones with justice. {3} The mountains will bring prosperity to the people, the hills the fruit of righteousness. {4} He will defend the afflicted among the people and save the children of the needy; he will crush the oppressor. {5} He will endure as long as the sun, as long as the moon, through all generations. {6} He will be like rain falling on a mown field, like showers watering the earth. {7} In his days the righteous will flourish; prosperity will abound till the moon is no more. {8} He will rule from sea to sea and from the River to the ends of the earth.
