'Prepare' in the Bible

Behold, I will send my messenger, and he shall prepare the way before me: and the Lord, whom ye seek, shall suddenly come to his temple, even the messenger of the covenant, whom ye delight in: behold, he shall come, saith the LORD of hosts.

"They'll be mine," says the LORD of the Heavenly Armies, "in the day when I prepare my treasured possession. I'll spare them, just as a man spares his own son who serves him.

And ye shall tread down the wicked; for they shall be ashes under the soles of your feet in the day that I prepare, saith Jehovah of hosts.
