Hour
Easton's Bible Dictionary 1897
First found in Dan. 3:6; 4:19, 33;5:5. It is the rendering of the Chaldee shaah, meaning a “moment,” a “look.” It is used in the New Testament frequently to denote some determinate season (Matt. 8:13; Luke 12:39).
With the ancient Hebrews the divisions of the day were “morning, evening, and noon-day” (Ps. 55:17, etc.). The Greeks, following the Babylonians, divided the day into twelve hours. The Jews, during the Captivity, learned also from the Babylonians this method of dividing time. When Judea became subject to the Romans, the Jews adopted the Roman mode of reckoning time. The night was divided into four watches (Luke 12:38; Matt. 14:25; 13:25). Frequent allusion is also made to hours (Matt. 25:13; 26:40, etc.). (See DAY.)
An hour was the twelfth part of the day, reckoning from sunrise to sunset, and consequently it perpetually varied in length.

our (sha`atha', she`a'; hora): Hour as a division of the day does not occur in the Old Testament; the term she`a' (sha`atha') found in Dnl, is Aramaic, and as used there denotes a short period or point of time of no definite length (Da 3:6,15; 4:33 (Hebrew 30); 5:5). The Greek hora is commonly used in the New Testament in the same way, as "that same hour," "from that hour," etc., but it also occurs as a division of the day, as, "the third hour," "the ninth hour," etc. The Hebrews would seem to have become acquainted with this division of time through the Babylonians, but whether before the captivity we are not certain. The mention of the sun dial of Ahaz would seem to indicate some such reckoning of time during the monarchy.
