Divrei Hayamim 27:23

וְלֹֽא־נָשָׂ֤א דָוִיד֙ מִסְפָּרָ֔ם לְמִבֶּ֛ן עֶשְׂרִ֥ים שָׁנָ֖ה וּלְמָ֑טָּה כִּ֚י אָמַ֣ר יְהֹוָ֔ה לְהַרְבּ֥וֹת אֶת־יִשְׂרָאֵ֖ל כְּכוֹכְבֵ֥י הַשָּׁמָֽיִם׃

But David did not take the number of them from twenty years old and under: because the Lord had said he would increase Yisra᾽el like the stars of the heavens.
