He Described Giving With 'In Secret' Three Times
In Matthew 6, Jesus uses the phrase 'in secret' three times in a row — once for almsgiving, once for prayer, once for fasting — forming a hidden structural triplet no single verse shows.
In Matthew 6, Jesus delivers three parallel instructions — on almsgiving (6:4), prayer (6:6), and fasting (6:18) — and in each case closes the unit with a nearly identical formula: God who sees 'in secret' will reward 'openly.' The repetition is not incidental. Each unit follows the same internal architecture: a negative command ('be not as the hypocrites'), a positive alternative ('when thou doest thine alms / prayest / fastest'), a location phrase placing the act 'in secret,' and then the reward clause citing the Father who 'seeth in secret.' The Greek word is kryptos (hidden, concealed) in all three instances, and the Father is the grammatical subject who 'sees' in each case — not a community, not an observer, not a record-keeper. What the triplet reveals is that the word 'secret' functions structurally as a hinge: the entire value of each practice depends on whether the act's audience is God alone or a human crowd. The same word that defines the location of the act also defines the qualifications of the witness. This three-part repetition of a single word in near-identical grammatical structures within a single discourse is unusual in the red-letter corpus. Jesus does not extend the 'in secret' formula to any other practice — not Sabbath-keeping, not vow-making, not tithing — making the selection of these three acts significant by its own boundary.

Matthew 6:4Matthew 6:6Matthew 6:18
That thine alms may be in secret: and thy Father which seeth in secret himself shall reward thee openly .
But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly .
That thou appear not unto men to fast, but unto thy Father which is in secret: and thy Father, which seeth in secret, shall reward thee openly .
Evidence Notes
Matthew 6:4 — 'That thine alms may be in secret: and thy Father which seeth in secret himself shall reward thee openly.' Matthew 6:6 — 'pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly.' Matthew 6:18 — 'That thou appear not unto men to fast, but unto thy Father which is in secret: and thy Father, which seeth in secret, shall reward thee openly.' The phrase 'in secret' (or its equivalent) appears in all three verses and only in these three within a single discourse block. No other practice in the red-letter corpus receives this label.
Greek Note
The Greek behind 'in secret' in all three verses is kryptos (κρυπτῷ), a dative form meaning 'in a hidden place.' The Father is described as 'the one seeing in secret' (ὁ βλέπων ἐν τῷ κρυπτῷ) in each instance — a grammatically parallel clause that functions as both description and justification for the instruction.
