Psalm 91:13
11 For he will order his angels to protect you in all you do. 12 They will lift you up in their hands, so you will not slip and fall on a stone. 13 You will subdue a lion and a snake; you will trample underfoot a young lion and a serpent. 14 The Lord says, “Because he is devoted to me, I will deliver him; I will protect him because he is loyal to me. 15 When he calls out to me, I will answer him. I will be with him when he is in trouble; I will rescue him and bring him honor.
LXX Psalm 90:13
11 because he will command his angels concerning you, to guard you in your ways. 12 Upon hands they will lift you, lest you strike your feet against a stone. 13 You will tread upon snake and serpent, and you will trample down lion and dragon. 14 For in me he hoped, and I will rescue him. I will shelter him because he knew my name. 15 He will invoke me, and I will listen to him. I am with him in affliction, and I will deliver and honor him.
Notes and References
"... The term ןיִנַּתּ sometimes appears to refer to an ordinary snake (e.g., Deuteronomy 32:33, Psalm 91:13). However, these too might bear mythological significance. Indeed, the LXX translates ןיִנַּתּ in Psalm 90:13 (= Masoretic text of 91:13) as δράκοντα ('dragon') ..."
