to reckon something up in the mind: to weigh it point by point and set it against something else
This is a bookkeeping word for the mind. It is built on the ordinary verb for reckoning or adding up a sum (λογίζομαι), and it means to draw up a mental account of something: to go back over it item by item, tally the total, and take that total into account before you act. Greek speakers still heard the counting-house in it, so it asks for deliberate mental work, not a passing thought.
In its one appearance, Hebrews 12:3, the reckoning is comparative. The readers are told to add up everything Jesus endured and set that sum beside their own weariness, so that their fatigue looks small next to his. The word sits inside a picture of a runner about to collapse, and it does the pivotal work of the sentence: once you have done the sums on what Christ bore, you find the strength not to give out.
Because the word blends three shades at once, no single English word carries it:
- adding a total up, as in a ledger
- weighing one thing against another on a scale
- steady, deliberate reflection on what you have counted
"Consider" is the usual English choice, but it is the palest of the options; "weigh" and "compare" each catch a real part of what the word is doing.
Disputed
Which shade of the verb is uppermost in Hebrews 12:3: comparative (setting Christ's endurance beside the readers' own), calculative (weighing and tallying his sufferings point by point), or meditative (plain reflective "consider").
