Day @ The Jews reckoned the day from sunset to sunset Leviticus:23:32). It was originally divided into three parts Psalms:55:17). "The heat of the day" ( 1Samuel:11:11; Nehemiah:7:3) was at our nine o'clock, and "the cool of the day" just before sunset Genesis:3:8). Before the Captivity the Jews divided the night into three watches, (1) from sunset to midnight Lamentations:2:19); (2) from midnight till the cock-crowing Judges:7:19); and (3) from the cock-crowing till sunrise Exodus:14:24). In the New Testament the division of the Greeks and Romans into four watches was adopted Mark:13:35). (See WATCHES.) The division of the day by hours is first mentioned in Daniel:3:6Daniel:3:15Daniel:4:19Daniel:5:5 . This mode of reckoning was borrowed from the Chaldeans. The reckoning of twelve hours was from sunrise to sunset, and accordingly the hours were of variable length John:11:9). The word "day" sometimes signifies an indefinite time Genesis:2:4; Isaiah:22:5; Hebrews:3:8, etc.). In Job:3:1 it denotes a birthday, and in Isaiah:2:12, Acts:17:31, and 2Timothy:1:18, the great day of final judgment.
Day's journey @ The usual length of a day's journey in the East, on camel or horseback, in six or eight hours, is about 25 or 30 miles. The "three days' journey" mentioned in Exodus:3:18 is simply a journey which would occupy three days in going and returning.
Daysman @ an umpire or arbiter or judge Job:9:33). This word is formed from the Latin diem dicere, i.e., to fix a day for hearing a cause. Such an one is empowered by mutual consent to decide the cause, and to "lay his hand", i.e., to impose his authority, on both, and enforce his sentence.
Daystar @ which precedes and accompanies the sun-rising. It is found only in 2Peter:1:19, where it denotes the manifestation of Christ to the soul, imparting spiritual light and comfort. He is the "bright and morning star" of Revelation:2:28Revelation:22:16. (Comp. Numbers:24:17.)
