Keeper; Keepers

From BibleEncyclopedia.Net

kēp´er, (mostly from שׁמר, shāmar; φύλαξ, phúlax):

The word is used of keepers of sheep, vineyards, doors, prisons (in Genesis 39:21 ff, ṣar; compare Acts 5:23), etc. In Ecclesiastes 12:3, “The keepers of the house shall tremble,” the allusion is to the decay of bodily powers, the “keepers” being specially the arms, which had become feeble through age.
