'Shouldest' in the Bible

Hast thou not heard that long ago I did it, and that from ancient days I formed it? Now have I brought it to pass, that thou shouldest lay waste fortified cities into ruinous heaps.

so I have long ago declared them to thee; before they came to pass I caused thee to hear them; lest thou shouldest say, Mine idol hath done them, and my graven image, or my molten image hath commanded them.

they are created now, and not long ago; and before this day thou hast not heard them, lest thou shouldest say, Behold, I knew them.

Thus saith Jehovah, thy Redeemer, the Holy One of Israel; I am Jehovah thy God, who teacheth thee for thy profit, who leadeth thee in the way that thou shouldest go.

and he saith, It is a small thing that thou shouldest be my servant to raise up the tribes of Jacob, and to restore the preserved of Israel; I have even given thee for a light of the nations, that thou mayest be my salvation unto the end of the earth.
