Find would be used if you were already manipulating the set in which that div may exist
<div class=".somewrapper">
<div>linda</div>
<div>jack</div>
<div>george</div>
</div>
<div class=".somewrapper">
<div>simon</div>
<div>peter</div>
<div>samantha</div>
</div>
$('.somewrapper').each(function(){
// something other js going on here
$(this).find('div').each(function(){
if ($(this).text()=='jack') $(this).css({color:'red'});
})
});
