'Blessest' in the Bible

And now come, I pray thee, curse me this people; for they are mightier than I: perhaps I may be able to smite them, and drive them out of the land; for I know that he whom thou blessest is blessed, and he whom thou cursest is cursed.

Thou dost satiate its furrows, thou smoothest its clods, thou makest it soft with showers; thou blessest the springing thereof.

Since otherwise, if thou blessest with the spirit, how shall he who fills the place of the simple Christian say Amen, at thy giving of thanks, since he does not know what thou sayest?
