'Wilt' in the Bible

My son, if thou wilt receive my words, And lay up my commandments with thee;

How long wilt thou sleep, O sluggard? When wilt thou arise out of thy sleep?

Wilt thou set thine eyes upon that which is not? For riches certainly make themselves wings, Like an eagle that flieth toward heaven.

For thou wilt heap coals of fire upon his head, And Jehovah will reward thee.
