Daleth (ד) is the fourth letter of the Hebrew alphabet. It marks the beginning of the next section of this psalm.
The poet feels deep pain and sadness but asks the Lord to give him strength. He wants to follow the Lord. Suffering and death may result from the Lord’s discipline (Psalms 118:17–18; 119:67, 71, 75), but his instruction renews the weary soul (see 119:12).
