From the dawn of their history, the children of Israel had the Torah and the ark which contained the Torah, and the rest of what Moses and Aaron had left behind, some of which were the remaining tablets
When they strayed and transgressed, God sent them Palestinian giants to rob them of it. They conquered the Jews and took away the ark . Their prophet then said that the sign of God’s approval of King Saul is that he should return unto them the ark. The angels arrived carrying the ark and placed it in Saul’s hands while the people stared. This was proof to the children of Israel that their prophet told the truth when he transmitted the divine command
(Their prophet further told them, “The sign of Saul’s kingship is that the Ark will come to you—containing reassurance from your Lord and relics of the family of Moses and the family of Aaron, which will be carried by the angels. Surely in this is a sign for you, if you ˹truly˺ believe.”) Al-Baqara 2:248
كَانَ عِنْدَ بَنِي إِسْرَائِيلَ التَّوْرَاةُ وَتَابُوتُ وَفِي التَّابُوتِ التَّورَاةُ وَبَقِيَّةُ مِمَّا تَرَكَ مُوسَى وَهَارُونُ وَمِنْهَا بَقَايَا الألْوَاحِ العَهْدِ الذِي كَانَ عِنْدَهُمْ مُنْذُ مَطْلِعِ تَارِيخِهِمْ .
لَمَّا ضَلُّوا وَبَغَوْا سَلَّط اللهُ عَلَيْهِمْ مَنْ سَلَبَهُمْ إيَّاهُ فَقَالَ لَهُمْ نَبِيُّهُمْ إنَّ عَلامَةَ رِضَا اللهِ عَلَى مُلْكِ طَالُوتَ هُوَ أنْ يَرُدَّ عَليكُمُ التَّابُوتَ . فَجَاءَتِ المَلاَئِكَةُ تَحْمِلُ التَّابُوتَ وَوَضَعَتْهُ بَيْنَ يَدَي طَالُوتَ وَالنَّاسُ يَنْظُرُونَ. وَفِي ذَلِكَ آيةٌ لِبني إسْرَائِيلَ عَلَى صِدْقِ نُبُوَّةِ نَبِيِّهِمْ،
(وَقَالَ لَهُمْ نَبِيُّهُمْ إِنَّ آيَةَ مُلْكِهِ أَن يَأْتِيَكُمُ التَّابُوتُ فِيهِ سَكِينَةٌ مِّن رَّبِّكُمْ وَبَقِيَّةٌ مِّمَّا تَرَكَ آلُ مُوسَىٰ وَآلُ هَارُونَ تَحْمِلُهُ الْمَلَائِكَةُ ۚ إِنَّ فِي ذَٰلِكَ لَآيَةً لَّكُمْ إِن كُنتُم مُّؤْمِنِينَ ﴿٢٤٨﴾)
