God used this word in its various forms 40 times in Scripture: 38 times to Israel in their Masoretic Text Old Testament; Once to Israel in their Koine Greek Old Testament book of John; and once to Israel’s Little Flock in their tribulation book of Hebrews.
Not every act of dedication was to God. One instance was about dedicating a new house to yourself, one instance is about dedicating silver to make idols, and two instances are about the dedications to the images of king Nebuchadnezzar.
