1 Psa 61:1-8. Neginah - or, Neginoth (see on Psa 4:1, title). Separated from his usual spiritual privileges, perhaps by Absalom's rebellion, the Psalmist prays for divine aid, and, in view of past mercies, with great confidence of being heard.
From the end - that is, places remote from the sanctuary (Deu 28:64).

2 heart is overwhelmed - literally, "covered over with darkness," or, "distress."
to the rock - (Psa 18:2; Psa 40:2).
higher than I - which otherwise I cannot ascend.

3 shelter ... and strong tower - repeat the same sentiment.

4 I will abide - So I desire to do (compare Psa 23:6).
trust in the covert, etc. - make my refuge, in the shadow (compare Psa 17:8; Psa 36:7).

5 the heritage - or, part in the spiritual blessings of Israel (Psa 21:2-4).
vows - implies prayers.

6 the king - himself and his royal line ending in Christ. Mercy and truth personified, as in Psa 40:11; Psa 57:3.

7 abide before God - literally, "sit as a king in God's presence," under His protection.

8 Thus for new blessings will new vows of praise ever be paid.
