Converting Lisp macros to Clojure

Hey everyone so I'm looking for a way to convert a lisp macro to work in Clojure I looked at some other posts talking about if you could convert but they really didn't show an example and was maybe looking for some help on this.

(defmacro n-of (n form) 
  (let ((lst-sym (gensym)) 
        (i-sym (gensym))) 
    `(let ((,lst-sym ())) 
       (dotimes (,i-sym ,n) 
         (push ,form ,lst-sym)) 
       (nreverse ,lst-sym))))

For lisp macro i assume Common Lisp macro.

(defmacro n-of [n & form]
  `(let [f# #(do ~@form)]
     (take ~n (repeatedly f#))))

where the & is like &rest or &body. #() is (lambda...). ~@ is ,@-. '~' is ','.
