Merge Item 1 of list 1 with item 1 of list 2 ?

What is the best way to combine list items in the manner below without using delimiters?

Edit: Number of list items may vary, but any two list will always have the same number of items.

{{“1”, “2”, “3”}, {“4”, “5”, “6”}}

Result: {“1 4”, “2 5”, “3 6”}

{{“1”, “2”, “3”, “4”}, {“5”, “6”, “7”, “8”}}

Result: {“1 5”, “2 6”, “3 7”, “4 8”}

Close, but yet so far…

set myList to {1, 3, 5, 7}
set myList_2 to {2, 4, 6, 8}

set newList to {}

repeat with n from 1 to (count of myList)
	set end of newList to n & item n of myList_2
end repeat


newList --> {{1, 2}, {2, 4}, {3, 6}, {4, 8}}

Need result to be {“1 2”, “3 4”, “5 6”, “7 8”}

Hi.

set {l1, l2} to {{"1", "2", "3"}, {"4", "5", "6"}}
set newlist to {}

repeat with i from 1 to (count l1)
	set end of newlist to (item i of l1) as text & " " & item i of l2
end repeat

newlist --> {"1 4", "2 5", "3 6"}

So awesome. Thank you Nigel Garvey.
