Word study diegeiro and egeiro

Word Study — διεγείρω (diegeirō) and ἐγείρω (egeirō)

ἐγείρω (egeirō) — the base verb, "to raise, to wake, to raise up." It's the workhorse resurrection verb in the NT: used for Jesus's own rising ("he is not here, he is risen," Matthew 28:6), for the raising of the dead in general (Matthew 10:8, John 5:21), and for future bodily resurrection (1 Corinthians 15:52, "the dead will be raised"). Outside of resurrection contexts, it's also just the ordinary word for standing someone up or waking them from sleep — the semantic range covers both from the start.

διεγείρω (diegeirō) — an intensified compound of ἐγείρω, formed with the prefix διά ("through, thoroughly"). The prefix sharpens the sense toward a full, decisive rousing rather than a partial stirring — "to wake completely," "to arouse fully." It's used of Jesus waking from sleep in the storm (Mark 4:39, Luke 8:24) and of Joseph's waking here in Matthew 1:24. It appears far less often than ἐγείρω and is never used of resurrection itself in the NT — it stays confined to literal waking.

The relationship: διεγείρω isn't a separate resurrection term borrowing power from ἐγείρω — it's ἐγείρω intensified for ordinary waking. Matthew chose διεγείρω, not bare ἐγείρω. Either verb can describe a man waking. The compound names a full waking; the shared root is what lets that waking sit near the Gospel's larger rising.
