'Shouldest' in the Bible

If thou shouldest say in thy heart, These nations are greater than I; how can I dispossess them?

and Jehovah hath accepted thee this day to be a people of possession to him, as he hath told thee, and that thou shouldest keep all his commandments,

so that he should make thee high above all the nations which he hath made, in praise and in name and in honour; and that thou shouldest be a holy people to Jehovah thy God, as he hath said.

It is not in the heavens, that thou shouldest say, Who shall go up for us to the heavens, and bring it to us, that we should hear it and do it?

And it is not beyond the sea, that thou shouldest say, Who shall go over the sea for us, and bring it to us, that we should hear it and do it?
