First furst ('echadh, ri'shon; proton, to proton, protos):
Of these words, which are those most frequently used for "first," ri'shon is from rosh, "the head, and is used for the highest, chief, etc.; also of time, the beginning, e.g. Genesis 8:13, in the first month"; in Isaiah 44:6, Isaiah 48:12, it is used of Yahweh as Eternal and solely Supreme-the First and the Last (compare Isaiah 41:4). Special usages are in connection with "firstborn," "first- fruit," etc.; proton is used of that which is first in order; but also of that which is first or chief in importance, etc. (Matthew 6:33, James 3:17). In 1 Timothy 1:15, Paul says Jesus came "to save sinners; of whom I am chief," literally, "first"; the same word is used by Jesus of the "first" of the commandments (Mark 12:29); where we read in 1 Corinthians 15:3, "I delivered unto you first of all," it is en protois ("in the foremost place"); "The first and the last" is applied to Christ as Eternal and Supreme (Revelation 1:17, Revelation 2:8, Revelation 22:13); protos is "the first day" (Matthew 26:17, Mark 16:9); in Matthew 28:1, Mark 16:2, Luke 24:1, John 20:1, John 20:19, Acts 20:7, it is mia ("one").
