The wonderful song in Palms 84 says the following:
4 Blessed are they that dwell in thy house: they will be still praising thee. Selah. 
5 Blessed is the man whose strength is in thee; in whose heart are the ways of them. 
6 Who passing through the valley of Baca make it a well; the rain also filleth the pools. 
7 They go from strength to strength, every one of them in Zion appeareth before God. 
٤ طُوبَى لِلسَّاكِنِينَ فِي بَيْتِكَ، أَبَدًا يُسَبِّحُونَكَ. سِلاَهْ. 
٥ طُوبَى لأُنَاسٍ عِزُّهُمْ بِكَ. طُرُقُ بَيْتِكَ فِي قُلُوبِهِمْ.

٧ يَذْهَبُونَ مِنْ قُوَّةٍ إِلَى قُوَّةٍ. يُرَوْنَ قُدَّامَ اللهِ فِي صِهْيَوْنَ.
