Psalms 44:2

Thou... with thy hand. — Literally, Thou, Thy hand, which may be, as in the Authorised Version, taken as accusative of instrument, or as a repeated subject.

And cast them out. — This entirely misses the meaning and destroys the parallelism. The Hebrew word is that used for a treo spreading its branches out; comp. Jeremiah 17:8; Ezekiel 17:6; Ezekiel 31:5, and especially Psalms 80:11, a passage which is simply an amplification of the figure in this verse, viz., of a vine or other exotic, planted in a soil cleared for its reception, and there caused to grow and flourish. The pronoun them in each clause plainly refers to Israel.

Thou, with thine hand, didst dispossess the heathen,
And planted them (Israel) in.

Thou didst afflict the peoples.
But didst make them to spread.
