Galilee and Judea · Biblical era; date uncertain

Matthew

Matthew worked as a tax collector before becoming a disciple. Tax work required arithmetic, rates, receipts, debt records, currency handling, and careful comparison between amounts owed and paid.

The person and the work

Biography

Matthew is presented in the Bible as a tax collector, record keeper, and writer in Galilee and Judea. The Gospel accounts identify Matthew at a tax booth, a role tied to collecting money and maintaining accountable records within a larger revenue system.

A tax amount may be a fixed charge or a rate applied to value. Either way, the collector must calculate, record, compare, and reconcile numbers accurately.

History, archaeology and the biblical record

Historical Record

Biblical record with documented tax context

No inscription has been securely tied to Matthew. The Gospel tradition remains the primary personal record, while Roman tax administration, customs stations, coinage, roads, and first-century Capernaum strongly support the setting of his work.

What the text records

The Gospels identify Matthew with tax collection, a job requiring totals, rates, records, currency conversion, receipts, and accountability.

What history supports

Roman and local tax systems are extensively documented, and archaeology at Capernaum confirms a busy lakeside settlement connected to fishing and trade routes.

What remains uncertain

No surviving tax ledger or inscription names Matthew, and later traditions about his life should not be confused with direct archaeological evidence.

What this hero added or preserved

Math inside the work

The Gospel accounts identify Matthew at a tax booth, a role tied to collecting money and maintaining accountable records within a larger revenue system.

Why the numbers mattered

A tax amount may be a fixed charge or a rate applied to value. Either way, the collector must calculate, record, compare, and reconcile numbers accurately.

Why this matters

The larger lesson

Matthew shows that mathematics is not limited to classrooms or famous theorems. It appears wherever people measure, count, compare, schedule, build, trade, record, or plan responsibly.

Timeline

  1. Biblical era

    Work described in the text

    The Gospel accounts identify Matthew at a tax booth, a role tied to collecting money and maintaining accountable records within a larger revenue system.

  2. Math connection

    A practical lesson that still applies

    A tax amount may be a fixed charge or a rate applied to value. Either way, the collector must calculate, record, compare, and reconcile numbers accurately.

Key idea

A rate connects an amount to a rule

Rates let the same rule apply to different totals. Matthew’s former work provides a practical setting for multiplication, percentages, and checking recorded payments.

Example

A 5% charge on 200 coins is 10 coins.

Try it yourself

Calculate a simple rate

A charge is 5% of 200 coins. What amount is due?

  1. Convert 5% to 0.05.
  2. Multiply 200 by 0.05.
Show the answer

200 × 0.05 = 10 coins.

Math at work

Modern work still uses the same habits

People in related work still use counting, measurement, estimates, records, and checks. Matthew provides a Bible-based example of mathematics serving real responsibility.

Keep curiosity alive

A little-known fact

A tax booth was a working place for money and records, not merely a symbolic location in the story.

What is not established

The text says Matthew used a particular modern tax formula.

What the record supports

The text identifies his occupation. Tax collection and record keeping normally require arithmetic, totals, comparison, and verification, but his specific accounting system is not preserved.
