The number 153, which is mentioned in the Gospel of John as the<br/>number of fish caught at the nocturnal fishing on Lake Tiberias<br/>appears as significant as it is mysterious.<br/><br/>Also the richness of its mathematical relations - it yields, e.g., the<br/>addition series or the triangular number of the seventeen, which is mentioned in the Mosaic writings quite often, and it represents the first Armstrong number - cannot explain the peculiar way of its mention: it stands alone, without further indication of measure as is the case with other numbers.<br/>It is mentioned without any further arithmetical or narrative context; it appears like a statement that contains a special but hidden meaning.<br/><br/>The work traces the meaning of the number on the basis of the Hebrew etymology.<br/>In the process, a hitherto unknown relation of this number to the<br/>story of camel and eye of a needle in the other three Gospels is revealed.
