112 Heb “I said,” meaning “I said to myself” = “I thought.”
113 Heb “I was about to be cut off.” The verb נִגְזָרְתִּי (nigzarti), Niphal perfect 1st person common singular from גָּזַר (gazar, “to be cut off”), functions in an ingressive sense: “about to be cut off.” It is used in reference to the threat of death (e.g., Ezek 37:11). To be “cut off” from the hand of the living means to experience death (Ps 88:6).
114 Heb “from a pit of lowest places.”
115 The verb could be understood as a precative, “hear my plea,” parallel to the following volitive verb, “do not close.”
116 Heb “my voice.”
117 The preposition ל (lamed) continues syntactically from “my plea” in the previous line (e.g. Ex 5:2; Josh 22:2; 1 Sam 8:7; 12:1; Jer 43:4).
