This verb fundamentally means to make something visible or evident — to show, demonstrate, or point out what was previously unknown. Jesus tells a disciple 'I will show you' whom to fear (Luke 12:5) and Paul says the Lord 'showed me' what he must suffer (Acts 9:16). But in the mouths of John the Baptist and Jesus, it takes on a sharper edge: 'Who warned you to flee from the wrath to come?' (Matt 3:7; Luke 3:7). Here the word moves from neutral demonstration to urgent admonition. The Swahili translation 'aliwaonya' (he warned them) captures the cautionary force that distinguishes this warning sense from simple showing.
