Переклад - Давньоєврейська-Англійська - תזכורת- הערב ארוע הפתיחה של הקזינסקי

He got the names wrong, and the opening means "hello hello" and not "welcome welome".
Also the speaker is singular and not plural.

No. It doesn't mean hello. Milkman, it is a Hebrew spelling for the arabic which means welcome, but even more than that. A simple hello doesn't begin to cover it. אהלן is the traditional greeting made when you welcome someone into your home, and it is quite a ceremony. Salam, shalom, and the like are hello. Ahlan means so very much more...welcome to my home...to my hospitality...to my tent...share with me in peace.

regarding the name...hard to say if it is Kazinski or Kazinsky since it is written in Hebrew as a proper name and difficult to translate into English because of the many spelling varieties. You are right, the speaker is singular...and it should read I just wanted...and thank you I will edit that.

Further to my last post: marhaba really means hello Ahlan means more: welcome, greetings would be good translations. What has happened here, is it has entered into Israeli Hebrew Slang..when we use it in Israel it is more welcome than anything...like when we have a guest who is going to sit down for coffee...or when someone wants to come over and I say Ahlan...I know this might seem pretty subjective, but it is slang, and it is how we use it. If I want to say hello, these days in Israel, we say "Hi" or Maneshma (losely translated as what's happening..how are you...etc.
