The word(s) "though" appears 144 time(s) in 137 verse(s) in Quran in Muhammad Pickthal translation.

(131) And when thou seest them their figures please thee; and if they speak thou givest ear unto their speech. (They are) as though they were blocks of wood in striped cloaks. They deem every shout to be against them. They are the enemy, so beware of them. Allah confound them! How they are perverted!

(132) Say (O Muhammad): Have ye thought: Whether Allah causeth me (Muhammad) and those with me to perish or hath mercy on us, still, who will protect the disbelievers from a painful doom?

(133) Say: Have ye thought: If (all) your water were to disappear into the earth, who then could bring you gushing water?

(134) though they will be given sight of them. The guilty man will long to be able to ransom himself from the punishment of that day at the price of his children

(135) Although he tender his excuses.

(136) On the day when hidden thoughts shall be searched out.

(137) Although the Hereafter is better and more lasting.
