'Blessest' in the Bible

Come now therefore, I pray thee, curse me this people; for they are too mighty for me: peradventure I shall prevail, that we may smite them, and that I may drive them out of the land: for I wot that he whom thou blessest is blessed, and he whom thou cursest is cursed.

Now therefore let it please thee to bless the house of thy servant, that it may be before thee for ever: for thou blessest, O LORD, and it shall be blessed for ever.

For Thou blessest the righteous, O Jehovah, As a buckler with favour dost compass him!

Thou waterest the ridges thereof abundantly: thou settlest the furrows thereof: 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?
