A post of duty is the placement at which one’s appointed obligation is performed. Scripture knows the concept by office. The priest had his daily course (Luke 1:8-9), the Levite his service, the watchman his wall, the gatekeeper his door, the soldier his rank, the elder his oversight, the deacon his table-service. "Wherefore stand having your loins girt about with truth" (Ephesians 6:14) — stand at your post. The faithful saint and the faithful Marine share an instinct: the post is the place you do not abandon, no matter how dull, dangerous, or thankless. Faithfulness is not romantic; it is showing up on the wall, in the watch, at the assigned hour — every morning, until relieved.
(Composite.) The fixed station at which one's appointed duty is performed; place of assigned obligation.
Post in Webster: “a station, or the place where a soldier or body of soldiers is stationed.”
Duty: “that which a person is bound, by any natural, moral, or legal obligation, to pay, do, or perform.” Joined: the location where the obligation is to be discharged.
Numbers 1:53 — "But the Levites shall pitch round about the tabernacle of testimony, that there be no wrath upon the congregation."
1 Chronicles 9:23 — "So they and their children had the oversight of the gates of the house of the LORD, namely, the house of the tabernacle, by wards."
2 Timothy 4:5 — "But watch thou in all things, endure afflictions, do the work of an evangelist, make full proof of thy ministry."
1 Corinthians 7:24 — "Brethren, let every man, wherein he is called, therein abide with God."
Modern Christianity treats vocation as elective and revisable; Scripture treats post as something one is placed in and accountable to.
1 Corinthians 7:24 is one of the more uncomfortable verses for modern hearers: let every man, wherein he is called, therein abide with God. Stay where you were placed. Bring God to that post.
The household, the workplace, the marriage, the church office — each is a post. The saint's instinct should match the Marine's: the post is the place you do not abandon. Permission to leave is required, not assumed.
Hebrew maamad (station, post) and Greek topos (place, post).
Hebrew maamad — station, post; the appointed standing-place.
Note: 1 Cor 7:24 is the New Testament's clearest stay-at-your-post verse.
"The post is the place you do not abandon."
"Stay where you were called; bring God to that post."
"Permission to leave is required, not assumed."
