Jesus or Jesus Christ is mentioned approximately 968 times. Christ (without Jesus) is mentioned an additional 286 times (approx). Making a total of approximately 1254 times
Moses is mentioned 852 times.
Abraham is mentioned 250 times and Abram 62 times making a total of 312 times.
David is mentioned 1141 times.
So Jesus/Jesus Christ/Christ occurs 113 times more than David.
Of course there are many references in the old testament to Jesus in the types and in the prophecies of the messiah, but I only listed the times the actual names occurred in all cases.
(I didn’t manually count the number of occurrences – I searched using 2 methods and got a discrepancy of 2 in one instance, so these numbers are likely to not be totally accurate)
