וַיְהִ֞י מִקֵּ֣ץ ׀ עֶשְׂרִ֣ים שָׁנָ֗ה אֲשֶׁ֨ר בָּנָ֧ה שְׁלֹמֹ֛ה אֶת־בֵּ֥ית יְהוָ֖ה וְאֶת־בֵּיתֽוֹ׃
און עס איז געװען צום סָוף פֿון צװאַנציק יאָר װאָס שלמה האָט געבױט דאָס הױז פֿון גאָט, און זײַן הױז,
Rashi
Now it came to pass at the end of twenty years The meaning is: at the end of twenty years that the entire construction had been completed: that of the House of the Lord seven years and that of his palace thirteen years, as it is written in I Kings (6:38, 7:1).
