Learn More →συναλίζω means “to assemble” and appears once in the New Testament, in Acts 1:4. In that context it describes Jesus and his followers as they are together while he gives a direct instruction about remaining in Jerusalem.

Root and Related Words
συναλίζω is connected with the preposition syn (σύν), “with” (Strong’s G4862). In Acts 1:4 the idea of “with” coheres naturally with the scene of persons gathered in one place and acting together under a shared instruction.

Occurrences
“Being assembled together with them, he commanded them, “Don’t depart from Jerusalem, but wait for the promise of the Father, which you heard from me.” (Acts 1:4)
Here συναλίζω frames the setting for a command. The wording “Being assembled together with them” places Jesus in the midst of a group and marks the moment as one of corporate presence rather than private conversation. The command that follows—“Don’t depart from Jerusalem, but wait…”—assumes a body of hearers who can act in concert, so the assembly functions as the immediate social context in which the instruction is delivered and received.

The verse also links the assembly to location and timing. The group is together at the point when Jesus speaks about not leaving “Jerusalem,” which makes the assembling more than a vague sense of association; it stands at the threshold of a concrete decision about where to remain. The assembly, then, is the gathered condition that precedes and supports the communal act of waiting that the command requires.
Finally, the verse’s internal logic ties assembling to authoritative communication. Because “he commanded them,” the assembling is not merely incidental background. It describes the situation in which instruction is issued to a collective, shaping the reader’s sense that what is being said is meant for those together as a group and not for scattered individuals acting independently.
Sense and Usage
In Acts 1:4, “to assemble” functions as a narrative hinge: it signals that the scene is one of gathered presence and prepares for a directive that has shared implications. The wording “assembled together with them” highlights togetherness as an actual state—people in company—so that the subsequent command can be understood as addressed to a community capable of common obedience (“Don’t depart… but wait…”). The idea of assembling does not carry the weight of the command itself; instead, it establishes the relational and situational frame in which the command is given and expected to be carried out.
The verse also shows that assembling can be closely linked with purposeful speech. The group’s being assembled is immediately followed by Jesus’ speaking, and the content of that speech concerns a collective posture of waiting for “the promise of the Father.” In this way συναλίζω supports a scene where instruction and expectation are shared. The assembling is the condition that makes the command publicly delivered and commonly heard, giving the moment a sense of unified attention and coordinated direction.
Imagery
The single occurrence evokes the simple, concrete image of a company gathered around a speaker at the moment of a decisive instruction. In Acts 1:4 the assembly is not described with visual details, but the language itself places emphasis on togetherness—an assembled group poised to remain in Jerusalem and to wait for what has been promised.
