Problems with Hebrew in datepicker - datepicker

Question

I am using datepicker and I want it to work in Hebrew.
I found this: https://jqueryui.com/datepicker/#localization
but I don't want the user to choose a language. I want ths datepicker to work only in Hebrew.
How can I do that?
I tried this:
$.datepicker.setDefaults($.datepicker.regional['he']);
i got an answer from Sooriya Dasanayake but now I am trying to add date range and that doesn't work:
from = $( "#from" ).datepicker({
defaultDate: "+4w",
changeMonth: true,
numberOfMonths: 3,
showButtonPanel: true,
showOn: "button",
showAnim:"blind",
onSelect: function( selectedDate ) {
$( "#from" ).datepicker( $.datepicker.regional[ "en-GB" ] );
$( "#locale" ).change(function() {
$( "#from" ).datepicker( "option",
$.datepicker.regional[ $( this ).val() ] );
})
}
})
.on( "change", function() {
to.datepicker( "option", "minDate", getDate( this ) );
}),
to = $( "#to" ).datepicker({
changeMonth: true,
numberOfMonths: 3,
showButtonPanel: true,
showOn: "button",
showAnim:"blind",
onSelect: function( selectedDate ) {
$( "#to" ).datepicker( $.datepicker.regional[ "en-GB" ] );
$( "#locale" ).change(function() {
$( "#to" ).datepicker( "option",
$.datepicker.regional[ $( this ).val() ] );
})
}
})
.on( "change", function() {
from.datepicker( "option", "maxDate", getDate( this ) );
});
function getDate( element ) {
var date;
try {
date = $.datepicker.parseDate( dateFormat, element.value );
} catch( error ) {
date = null;
}
return date;
}
});

Try this..
jQuery(function($){
$.datepicker.regional['he'] = {
closeText: 'סגור',
prevText: '<הקודם',
nextText: 'הבא>',
currentText: 'היום',
monthNames: ['ינואר','פברואר','מרץ','אפריל','מאי','יוני',
'יולי','אוגוסט','ספטמבר','אוקטובר','נובמבר','דצמבר'],
monthNamesShort: ['ינו','פבר','מרץ','אפר','מאי','יוני',
'יולי','אוג','ספט','אוק','נוב','דצמ'],
dayNames: ['ראשון','שני','שלישי','רביעי','חמישי','שישי','שבת'],
dayNamesShort: ['א\'','ב\'','ג\'','ד\'','ה\'','ו\'','שבת'],
dayNamesMin: ['א\'','ב\'','ג\'','ד\'','ה\'','ו\'','שבת'],
weekHeader: 'Wk',
dateFormat: 'dd/mm/yy',
firstDay: 0,
isRTL: true,
showMonthAfterYear: false,
yearSuffix: ''};
$.datepicker.setDefaults($.datepicker.regional['he']);
});
