John Gill Commentary Psalms 31:20

"In the covert of thy presence wilt thou hide them from the plottings of man: Thou wilt keep them secretly in a pavilion from the strife of tongues." — Psalms 31:20 (ASV)

You shall hide them in the secret of your presence
That is, those that fear the Lord and trust in him; and therefore they are called his "hidden ones", (Psalms 83:3); these the Lord preserves in times of trouble and danger, and when his indignation is out against others; and so the Targum is, "in the time of your anger"; see (Isaiah 26:20); the presence of God is their protection, he himself is a wall of fire round about them, his favour compasses them as a shield, and they are kept as in a garrison by his power; see (Psalms 91:1); and that "from the pride of man", which otherwise would at once oppress, bear them down, and destroy them, (Psalms 124:1–5);

you shall keep them secretly in a pavilion from the strife of
tongues ;
which are as a sharp sword, and from which proceed devouring words, such contradiction of sinners as Christ endured; not that the saints are kept free from the reproaches of men, from the lash of their tongues, but from being harmed by them; and sometimes, through the strivings and contentions of men with one another, they privately escape and are preserved, as the Apostle Paul was, (Acts 23:9Acts 23:10).
