'Unto' in the Bible

The burden of a word of Jehovah unto Israel by the hand of Malachi:

And ye have known that I have sent unto you this charge, For My covenant being with Levi, Said Jehovah of Hosts.

And this a second time ye do, Covering with tears the altar of Jehovah, With weeping and groaning, Because there is no more turning unto the present, Or receiving of a pleasing thing from your hand.

Lo, I am sending My messenger, And he hath prepared a way before Me, And suddenly come in unto his temple Doth the Lord whom ye are seeking, Even the messenger of the covenant, Whom ye are desiring, Lo, he is coming, said Jehovah of Hosts.

Even from the days of your fathers Ye have turned aside from My statutes, And ye have not taken heed. Turn back unto Me, and I turn back to you, Said Jehovah of Hosts. And ye have said, 'In what do we turn back?'

Bring in all the tithe unto the treasure-house, And there is food in My house; When ye have tried Me, now, with this, Said Jehovah of Hosts, Do not I open to you the windows of heaven? Yea, I have emptied on you a blessing till there is no space.
