The first occurrence.
The lion’s whelps have not trodden it, nor the fierce lion passed by it. Job 28:8
(In the Scripture Picture: … And as a bride adorns herself with her jewels. Isa 61:10)
The primitive root.
Strong’s H5710 עדה, adah, a primitive root meaning “to continue on, to pass on, to put on (to adorn), to advance on, to remove.” The 3-letter root is ayin + dalet + hey:
ayin ע = the eye, thus watch, know, shade
dalet ד = the door, thus enter, move, hang
hey ה = the man with upraised arms, thus look, reveal, wonder, worship, breath
The story: Watching (ayin) at the door (dalet) of worship (hey), in the sense of coming to a place, time, or event that is repeated again and again, such as the feast cycle, the tabernacle of meeting, or memorial days or landmarks. Thus daughter words have the sense of continuing on, passing on, putting on, or advancing on.
