Abad & Shamar עָבַד · שָׁמַר
A job description, in two verbs
Adam is put into the garden “to dress it and to keep it.” Two ordinary verbs — abad, serve or work; shamar, keep or guard. Ordinary alone. But watch what happens when the Bible uses them together, about a holy place.

He tends the grounds by day and locks the doors at night. One man, two duties: care and guard. Every church, every palace, every treasury has someone whose job is exactly these two verbs.
The pair, in its other home
Numbers 3 is the Levites’ job description at God’s tent — and it is Adam’s two verbs, side by side. Numbers 18:5–7 keeps the pair for the priests’ charge. In the books of Moses, when serve-and-guard land together at a holy place, it is priests’ work.
And follow the second verb one chapter forward: when the man is driven out, the keeping does not stop. It changes hands. The cherubim now shamar the way — the very task the man was given and dropped. A guard implies something to guard against; chapter 3 shows you what came in.
Serve-and-guard is a bright star of the sunrise sky, joined to the trees it was set to keep.
Open this scene’s sky →Each verb alone is common and secular — farmers abad fields and shepherds shamar flocks — so this is an argument from the pair and the setting, not from either word. On the most common reading, the Hebrew verbs point at the garden itself (“serve it, guard it”) — though the suffixes are debated, so we won’t build on them. Either way, “worship and obey” is more than the words say. The claim is a priestly vocation, shown by where the pair lives.
