Variables
Genesis 17:5
God renamed Abram to Abraham, and that is exactly how a variable works. Learn what a variable is, what "=" really means, and what happens to the old value when you reassign it.
the basics
If / else
Joshua 24:15
Joshua gave Israel a fork in the road, and every program has the same thing: a question that's either true or false. Learn how if and else decide which code runs, why indentation matters, and why only one branch ever runs.

The missing number
Luke 15:4-7
A shepherd with 100 sheep notices one is missing. Programmers get the same puzzle in interviews: the numbers 1 to 100 with one missing. Learn the slow way, the shepherd's way, and why one pass is enough.

Breadth-first search
Exodus 13:17
Leaving Egypt, the shortest road ran up the coast. Breadth-first search finds that road by exploring one step at a time. Exodus 13:17 says God chose not to take it, and that teaches us something about what "shortest" leaves out.
