The Quran

وَأَوحَينا إِلىٰ موسىٰ وَأَخيهِ أَن تَبَوَّآ لِقَومِكُما بِمِصرَ بُيوتًا وَاجعَلوا بُيوتَكُم قِبلَةً وَأَقيمُوا الصَّلاةَ ۗ وَبَشِّرِ المُؤمِنينَ

Muhammad Asad

And [thus] did We inspire Moses and his brother: "Set aside for your people some houses in the city, and [tell them], 'Turn your houses into places of worship,¹ and be constant in prayer!' And give thou [O Moses] the glad tiding [of God's succour] to all believers."

Lit., "a direction of prayer" (qiblah) - a metaphor meant to impress upon the children of Israel that their only salvation lay in God-consciousness and unceasing devotion to Him. The primary meaning of misr - usually rendered as "Egypt" - is "city" or "metropolis".
