40 Days and Forty Years: Testing in the Wilderness

Several key biblical stories link a wilderness (or desert) experience with the number 40, often marking a season of testing, transition, or preparation.

Major Wilderness “40” Stories

The number 40 is often associated with testing and preparation in the Bible. It is especially associated with the wilderness where people learn to trust in their Lord.

  • Israel in the wilderness – 40 years
    After the exodus, Israel wandered in the wilderness for forty years as a time of judgment, discipline, and formation before entering the promised land (for example, Deuteronomy 8:2–5). This extended “wilderness forty” becomes the backdrop for how later texts understand testing and trust.

  • Moses on Sinai – 40 days and nights
    Moses remained on Mount Sinai, in a harsh, mountainous wilderness, for forty days and forty nights when receiving the law from God (Exodus 24:18; see also Exodus 34:28). This is a period of fasting, intense encounter, and covenant revelation.

  • Elijah to Horeb – 40 days and nights
    After fleeing Jezebel, Elijah journeyed “forty days and forty nights to Horeb the mount of God” (1 Kings 19:8). Strengthened by food given by an angel, he travels through the wilderness to meet God in the “sound of sheer silence,” another pattern of exhausted prophet, desert, and divine renewal.

  • Jesus’ temptation – 40 days in the wilderness
    In the Gospels, Jesus is “led by the Spirit in the wilderness” for forty days, fasting and being tempted by the devil (Matthew 4:1–2; Luke 4:1–2). This recapitulates Israel’s forty years in the wilderness and Moses’ and Elijah’s forty-day encounters, but Jesus remains faithful where others failed.

These are not all labeled explicitly as “wilderness,” but they echo the same pattern of judgment, transition, and divine action associated with forty:

  • The flood – 40 days and nights of rain
    During Noah’s time it rained for forty days and forty nights (Genesis 7:12). While the setting is water, not desert, later Christian reflection often groups this with other “forty” periods as a global “wilderness” of uncreation and new beginning.

  • Other 40-year periods
    There are several 40-year spans that, while not always described with wilderness language, share the theme of testing and transition (for example, periods of oppression or rest in Judges, or Moses’ forty years in Midian before the exodus).

For Lent, the most directly parallel wilderness “40” narratives to place alongside Matthew 4:1–11 are Israel’s forty years in the desert, Moses’ forty days on Sinai, and Elijah’s forty days to Horeb, which are connected as the background for Jesus’ forty days in the wilderness.
