'May' in the Bible

And now, I pray you, entreat the favor of God, that he may be gracious unto us: this hath been by your means: will he accept any of your persons? saith Jehovah of hosts.

And ye shall know that I have sent this commandment unto you, that my covenant may be with Levi, saith Jehovah of hosts.

Bring ye the whole tithe into the store-house, that there may be food in my house, and prove me now herewith, saith Jehovah of hosts, if I will not open you the windows of heaven, and pour you out a blessing, that there shall not be room enough to receive it .
