for the measurement of time, only once mentioned in the Bible,
erected by Ahaz (2 Kings 20:11; Isa. 38:8). The Hebrew word
(ma'aloth) is rendered "steps" in Ex. 20:26, 1 Kings 10:19, and
"degrees" in 2 Kings 20:9, 10, 11. The "ma'aloth" was probably
stairs on which the shadow of a column or obelisk placed on the
top fell. The shadow would cover a greater or smaller number of
steps, according as the sun was low or high.

Probably the sun-dial was a Babylonian invention. Daniel at
Babylon (Dan. 3:6) is the first to make mention of the "hour."
