'Day' in the Bible

for your contribution to the good news from the first day till now,

having been confident of this very thing, that He who did begin in you a good work, will perform it till a day of Jesus Christ,

for your proving the things that differ, that ye may be pure and offenceless -- to a day of Christ,

the word of life holding forth, for rejoicing to me in regard to a day of Christ, that not in vain did I run, nor in vain did I labour;

circumcision on the eighth day! of the race of Israel! of the tribe of Benjamin! a Hebrew of Hebrews! according to law a Pharisee!
