quran:2:248 –

And their prophet said to them, "Indeed, a sign of his kingship is that the chest will come to you in which is assurance from your Lord and a remnant of what the family of Moses and the family of Aaron had left, carried by the angels. Indeed in that is a sign for you, if you are believers."  

And their prophet said to them, after they had demanded a sign of his kingship: ‘The sign of his kingship is that there will come to you the Ark, a chest containing the images of the prophets, which God sent down to Adam, and which was handed down to them ˹sc. the Israelites˺, until the Amalekites seized it from them in battle. They used to commence fighting invoking it before their enemy and marching behind it, as well as experience peacefulness in its presence, as God says: therein is a Spirit of Peace, reassurance for your hearts, from your Lord, and a remnant of what the folk of Moses and the folk of Aaron left behind, which were Moses’s pair of sandals and his staff, Aaron’s turban, a measure (qafīz) of the manna that used to come down on them, and the pieces of the broken tablets, the angels bearing it (tahmiluhu l-malā’ikatu, the circumstantial qualifier referring to the subject of the verb ya’tiyakum, ‘there will come to’). Surely in that shall be a sign for you, of his kingship, if you are believers’. The angels bore it between the earth and the sky while they gazed at it, until finally they placed it before Saul. They then acknowledged his kingship and hastened to enlist in the ˹holy˺ struggle, and he chose seventy thousand of their young men.
القرآن:٢:٢٤٨ –

وَقَالَ لَهُمْ نَبِيُّهُمْ إِنَّ آيَةَ مُلْكِهِ أَنْ يَأْتِيَكُمُ التَّابُوتُ فِيهِ سَكِينَةٌ مِنْ رَبِّكُمْ وَبَقِيَّةٌ مِمَّا تَرَكَ آلُ مُوسَىٰ وَآلُ هَارُونَ تَحْمِلُهُ الْمَلَائِكَةُ ۚ إِنَّ فِي ذَٰلِكَ لَآيَةً لَكُمْ إِنْ كُنْتُمْ مُؤْمِنِينَ  

{وقال لهم نبيهم} لما طلبوا منه آية على ملكه {إن آية ملكه أن يأتيكم التابوت} الصندوق كان فيه صور الأنبياء أنزله الله على آدم واستمر إليهم فغلبهم العمالقة عليه وأخذوه وكانوا يستفتحون به على عدوهم ويقدمونه في القتال ويسكنون إليه كما قال تعالى {فيه سكينة} طمأنينة لقلوبكم {من ربكم وبقية مما ترك آل موسى وآل هارون} أي تركاه هما، وهي نعلا موسى وعصاه وعمامة هارون وقفيز من المن الذي كان ينزل عليهم ورضاض من الألواح {تحمله الملائكة} حال من فاعل يأتيكم {إن في ذلك لآية لكم} على ملكه {إن كنتم مؤمنين} فحملته الملائكة بين السماء والأرض وهم ينظرون إليه حتى وضعته عند طالوت فأقروا بملكه وتسارعوا إلى الجهاد فاختار من شبابهم سبعين ألفاً.
