Exploring the Meaning of Eiseimi in Greek

εἴσειμι means “to enter,” marking movement from outside to inside a defined space. In the New Testament it is used for entering the temple, entering a gathering with leaders, and priests’ repeated entrance into the tabernacle’s first room.

Root and Related Words

εἴσειμι is related to eis (εἰς), “toward” (Strong’s G1519), a term of direction that points movement toward a goal or destination.

Occurrences

“Seeing Peter and John about to go into the temple, he asked to receive gifts for the needy.” (Acts 3:3)

Here εἴσειμι frames a moment at the threshold of sacred space: Peter and John are “about to go into the temple.” The word situates them on the verge of entry, so that the man’s request happens in the setting of anticipated movement inside. The scene’s tension depends on that impending entrance: the action is not a casual pass-by but a purposeful going-in, and the man times his asking to the moment when worshipers are headed inward.

“The day following, Paul went in with us to James; and all the elders were present.” (Acts 21:18)

In this narrative, εἴσειμι describes Paul’s going in “with us to James,” placing the movement within the social and communal structure of the church. The entrance is not into a building identified by name (as the temple is), but into an assembled presence: James is there, and “all the elders were present.” The verb carries Paul across a boundary into a meeting where leadership is gathered. It also highlights the shared nature of the approach—Paul does not enter alone but “with us,” emphasizing accompaniment and coordinated access to those inside.

“Then Paul took the men, and the next day purified himself and went with them into the temple, declaring the fulfillment of the days of purification, until the offering was offered for every one of them.” (Acts 21:26)

εἴσειμι here is embedded in a sequence of ordered actions: Paul “took the men,” “purified himself,” and “went with them into the temple.” The entrance is the transition point that connects preparation outside with ritual action inside. Because the verse continues with “declaring the fulfillment of the days of purification, until the offering was offered,” the entry functions as the gateway to a process that unfolds within temple practice. The verb thus carries more than simple motion; it marks the moment when purification and companionship culminate in crossing into the temple precincts where the declared days and the offering have their setting.

“Now these things having been thus prepared, the priests go in continually into the first tabernacle, accomplishing the services,” (Hebrews 9:6)

In Hebrews, εἴσειμι is used in a patterned, ongoing sense: “the priests go in continually into the first tabernacle.” The verb still denotes entrance, but the scene is structured by repetition (“continually”) and by purpose (“accomplishing the services”). The mention of “these things having been thus prepared” places the entrance within an ordered arrangement of sacred space and ritual readiness. The priests’ entering is not an isolated event but a regular movement into the “first tabernacle,” and the verb highlights the recurring passage into a specific area where appointed duties are carried out.

Sense and Usage

Across these passages, εἴσειμι consistently marks entry into a defined interior, and the definition “to enter” is expressed through spaces that function as boundaries between outside and inside. In Acts 3:3 the temple is the destination, and the word places the reader at the moment just before that boundary is crossed; entry is imminent and supplies the setting for a request for “gifts for the needy.” In Acts 21:18 the destination is a meeting with James where “all the elders were present,” so the entry is into the sphere of communal leadership; it signals gaining access to those gathered within. In Acts 21:26 the entrance into the temple follows purification and is paired with Paul’s accompaniment of others (“with them”), portraying entry as the step that introduces an extended, structured process leading “until the offering was offered.” In Hebrews 9:6, the same movement is portrayed as a continual rhythm: entering is the repeated prerequisite for “accomplishing the services” in the first tabernacle.

Two features stand out in how εἴσειμι functions in these contexts. First, the verb often brings with it a sense of purposeful approach: those who enter do so with intention—Peter and John going into the temple, Paul going in to James, Paul going into the temple after purification, priests going in to perform services. The motion is directed and tied to an activity expected on the inside. Second, εἴσειμι helps the text organize action around thresholds. What happens outside (a man asking, companions approaching, purification) is distinguished from what happens within (meeting the elders, declaring fulfillment, offerings, services). The word therefore serves as a narrative hinge, marking the crossing that changes what actions become possible and where they occur.

Imagery

The passages attach εἴσειμι to the imagery of sacred and communal interiors—temple and tabernacle—and to the orderly movement of people into places where worship, leadership, and service occur. Whether it is worshipers nearing the temple gate (Acts 3:3), a group entering to meet recognized leaders (Acts 21:18), companions entering the temple in connection with purification and offerings (Acts 21:26), or priests repeatedly entering the first tabernacle to perform their work (Hebrews 9:6), the verb paints entry as a decisive step into a space marked off for particular actions.
