SIBI-P1 G1210-15

it is binding

Rootδέω (deō)
Core Meaningsbind, tie, fasten, restrain, obligate
Semantic Rangeto bind physically, to tie or fasten, to restrain, to obligate, to be under obligation, to be necessary, to be compelled by circumstance or divine purpose
Conceptual SignificanceIn the New Testament, δεῖ often expresses divine necessity—what is "binding" according to God’s will or redemptive plan. It frames events, especially in the life and mission of Messiah, as bound by divine purpose rather than mere human circumstance.
Morphological NotesVerb; present active indicative, 3rd person singular (Gr,V,IPA3,,S). Though from δέω (to bind), this form functions impersonally, expressing necessity as an ongoing binding obligation.
Rendering RationaleThe form δεῖ is present active indicative, 3rd person singular, used impersonally. Rendering it as "it is binding" preserves the root sense of δέω (to bind) while reflecting the present tense and indicative mood, conveying an ongoing state of obligation or necessity rather than a simple modal "must."
