From Textus Receptus
It is necessary.
δει, the third person of δεω, is commonly used impersonally in classical Greek. This usage is less common, but frequent, in the N.T. δει indicates a necessity in the nature of things rather than a personal obligation; it describes that which must be done.
οφειλει indicates rather the personal obligation; it is that which is proper, something that ought to be done.
