The Greek word 'baptizo', which is translated 'baptize' in the English Bible, does not mean to sprinkle; it means to completely wash and immerse in a liquid (see the definitions in the concordances of Robert Young and James Strong).
Neno la Kiyunani ‘baptizo, ambalo limetafsiriwa ‘batiza’ katika Biblia za kiswahili halina maana ya kunyunyuzia; lina maana kamili kuosha na kutumbukiza ndani ya maji (tazama kwenye mfuatano wa maneno -concordances- ulioandikwa na Robert young na James Strong).
