Jeremiah 32: 37-40 'I will gather them out of all the countries where I drove them in my anger, fury and great wrath; and I will bring them back to this place and have them live here in safety. They will be my people, and I will be their God. I will give them singleness of heart and singleness of purpose, so that they will fear me forever - this will for their own good and for the good of their children after them. I will make with them an everlasting covenant not to turn away from them, but to do them good; I will put fear of me in their hearts, so that they will not leave me.
Yehovah is a combination of the three Hebrew forms of the verb "to be": Hayah (he was), Hoveh (he is), and Yihyeh (he will be)
